@JasSmith Well there is a whole discussion to be had about banning media who is spouting lie after lie after lie and are propaganda machines for the respective regimes.
But before you just assume censorship... try it yourself. I can open rt.com, tass etc and search for them.
Sometimes the search result are all nerfed to hell, but they are there.
And some pages (Zwezda) seem to have blocked access from my country at least, but that's on their site & RT does not have a valid certificate...
