vk.com works as a replacement for facebook. Telegram works as a replacement for twitter. The US won’t be able to ban those without going full China on them.
The only thing this removal does is it educates people how to avoid censorship. Russians learned how to avoid Putin’s censorship of Telegram, surely Americans will figure that out as well.
Ah, actually I’m wrong, there’s another thing it does. It divides people even further. But that might be the goal anyway.
