At such moments, one should often first of all think about the fact that behind the general tinsel of such laws hides something much more important than the rise in the price of communication services, albeit 3-4 times.
SWIFT. One of the laws of the Yarovaya package concerns the international bank transfer system SWIFT. Why? Because this system does not use Russian cryptography for data encryption. More than 80% of settlements of most financial institutions in the world use this system. If this law is adopted, communication between Russian banks and foreign ones will be legally prohibited. What will result in the collapse of the Russian banking system. It is noteworthy that in 2014 Russia was already under the threat of being disconnected from SWIFT in the manner of sanctions. There is one precedent for disconnecting the entire country from this system, in 2012 Iran was disconnected from it. The consequence is the impossibility of foreign trade. For example, the inability to receive payments for export oil. The question of how and why this law ended up in the package signed by the President of Russia today remains open.
This is the rise in the price of communication services.
Because the "Yarovaya package" (more precisely, the Yarovaya-Ozerov package) obliges companies providing communication services (cellular and Internet) to accumulate and store information about all user actions (that is, in fact, store all traffic) for 6 months. These are huge amounts of information, for the storage of which it is necessary to create infrastructure, purchase and adjust equipment, areas, etc. All this requires huge investments, which the companies, not being charitable, must somehow recoup. The only legal way to recoup such investments is to raise the prices of the services provided.
