What will be the most used social networks in 2020?

It is clear that Facebook, Instagram, WhatsApp, Twitter, TikTok will be top. But we will have some surprises. Reddit is one of them. I notice that this social network is growing a lot.Another surprise, this time negative, is the fact that some countries, former members of the Soviet Union, are preparing in a masked form to ban access to Google, YouTube, Facebook and other sites. They do this by taxing these companies. This taxation will cause companies to block users from these countries from accessing these sites. It is true that it may be a partial blockade. That is, only certain services will be blocked. Companies do not want this. But the governments of these countries want that.
 It is true that only Western companies will be taxed. The Russian ones will not be taxed. So they will replace Facebook with Vkontakte and Odnoklassniki. Google will be replaced by Yandex.ru and Mail.ru. YouTube is likely to be replaced by Rutube. I should point out that anyway these sites are very popular in these countries. The first example of a country that comes to mind is the Republic of Moldova. The pro-Russian government is preparing to do so somewhere in the spring of next year.
