You mean the TV station lost broadcasting-rights, or you mean the website it actually banned? Cause the website is certainly accessible for me from my European country, although that does not rule out that it is banned in some European countries.

The website rt.com is banned in the whole EU due to a decret by von der Leyen which bypassed parliament. It's trivial to bypass since it's "only" a DNS block but it's still censorship (no matter how you think about the content of RT). Same for Sputnik and the relevant TV channels.
