Are they banning any TV channels from hostile countries? RT, for example can be watched by Americans without restriction.

RT is required to register as a foreign agent in the US and is required to disclose information regarding its activities in the country or be subject to civil and criminal penalties for non-compliance. So I would not say it's able to operate without restriction.

They will soon!

Lmao these people are rubes. It's like every other bs "national security" argument.

Expect Yandex, VK, RT, Sputnik, SCMP, etc. to be banned as well under similar pretenses.

"Comrades! We can not let these Western dogs infect our proud Soviet minds with this 'Radio Free Europe'!"

They can if they choose to do so. Its not trademark law, just because a government doesnt do something doesnt mean it cannot do something
