Translated by Walter Lippmann for CubaNews.

Although the damages of the US blockade are not exclusive to the Communications sector, this unfair policy continues to be the main impediment to a better flow of information and a wider access to the internet and information and communication technologies in general by the Cuban people

Each month that elapsed from April to December 2020, caused damages for Cuba of more than seven million dollars, about 65 million in that period, only in the Communications sector.

The data was offered this Wednesday at a press conference by Wilfredo González Vidal, First Deputy Minister of Communications, when he updated on the damages caused by the economic, commercial and financial blockade that the United States Government maintains against Cuba, which worsened even more during the administration of Donald Trump.

Although the damages of the US blockade are not exclusive to this sector - they affect the whole of society as a whole - this unjust policy continues to be the main impediment to a better flow of information and a wider access to the internet and information technologies. and communication in general by the Cuban people, said the First Deputy Minister. Connectivity is made more expensive, access to certain platforms and technologies is prohibited, and cyberspace is used to try to subvert the country's political system, he said.

In this last point, González Vidal exemplified with the Internet Task Force, an entity created in 2017 by the United States Government as a mechanism to influence the internal order of the country and determine the efforts in the development of the Internet, an issue that by its own decision and sovereign is promoted by the Government of Cuba as part of the strategy of the process of computerization of society.

Points to take into account

When referring to the main effects generated by this genocidal policy of the United States, the First Deputy Minister of Communications said that they could be summarized in several fundamental questions.

The first is the limitation that Cuba has for the supply of technologies and equipment produced under license or using American components, which implies that it is necessary to go to the purchase in much more distant markets. For this concept, the greatest effects caused by the blockade in the Communications sector are quantified, with more than 90 percent of the 65 million calculated.

There is an important limitation on this issue, and that is that Cuba cannot acquire items that contain more than ten percent of US components, a measure that the United States Department of Commerce has intensified since October 2019.

The foregoing makes it impossible to access high-performance equipment that leads their respective markets. For example, the company Emerson Electric, which is dedicated to energy systems, the company Western Pacific Telecommunications, responsible for supplying external plant hardware - for fixed telephone lines and other issues - and the company Erico, which markets electrical systems advanced, are not available to Cuba as a result of the blockade.

Hence, the technologies that today support the public telecommunications service are marked by having been obtained from companies located geographically very distant from our country. This has repercussions on Etecsa's investments, and slows down the company's computerization process.

Another point highlighted by Wilfredo González Vidal was the effects on income from the export of services. There are limitations on foreign suppliers to enter into contracts for fear that their company will be sanctioned by the United States, and that implies that Cuba must assume financial and commercial risks.

In this specific case, as a consequence of the activation of Title III of the Helms-Burton Act, the American Airlines company decided to suspend the direct postal service between the United States and Cuba, González Vidal said. Thus, the Correos de Cuba Business Group had to find an alternative to guarantee universal postal service and decided to route it through Panama, as a third country. This action increased the price of the tariff - assumed by the postal operator -, but made the price of the kilogram of the postal item rise twice. Losses do not fall on the citizen, but delays in mail delivery do.

Error 403

Who in Cuba has not encountered a 403 error when trying to navigate certain internet pages? This is due to the fact that these web providers cannot allow Cubans to enter their platforms, since as companies they are subject to the laws of the United States, and this prohibits Cuba from blocking access to those services.

The list, unfortunately, grows. To the about 20 Google websites that are not accessible today, Zoom can be added more recently. The video chat platform became popular after the start of the COVID-19 pandemic, as it is a useful tool that allows maintaining communication with the necessary social distancing. Zoom is used in many areas, and it is the platform adopted by official international organizations for their meetings. But Zoom is blocked for Cuba.

This has the consequence that our country is unable to participate on equal terms with the rest of the member states of the United Nations.

Among the most popular sites that Cuba cannot access today are also those of Nvidia, Oracle, Dell and Adobe, just to mention a few.

The president of the Informatics and Communications Business Group, Ariadne Plasencia Castro, added at the meeting that the blockade prevents a better use of the possibilities of our professionals, as they are restricted in their access to these platforms, and forced to innovate to keep vital work systems running in the country's communications.

Plasencia Castro stated that the lack of parts for three teams for the deployment of fiber optics interrupted their operations, and therefore it has not been possible to advance more quickly in the installation of the infrastructure necessary to support a higher stage in the computerization process of the society.

Meanwhile, Ailyn Febles Estrada, president of the Cuban Information Technology Union (UIC), a civil society organization with five years of creation that brings together more than 8,000 engineers and specialists in the field, pointed out that the methodology for calculating damages in These damages have to be rethought, as there are many intangible elements that affect the successful development of new technologies in Cuba today.

Febles Estrada referred to the self-employed sector. In experiences lived by members of the UIC, he said, when conducting negotiations with foreign clients they have been unable to finalize them because they do not have access to basic industry issues such as repositories for version control, communication platforms or payment systems widely used in all the world.

The panelists agreed, however, that Cuba will continue to denounce this hostile policy of the United States Government, while working to promote computerization. In this sense, more than 64 percent of Cubans access the internet today, and mobile telephony has 6.6 million users. 4G networks are growing, and 76 percent of the population already has digital television signal coverage. However, it is important to put faces to the bits and bytes that this Archipelago has blocked by a stubborn neighbor who has not changed his attitude for more than 60 years.
