RT was targeted multiple times in the past - this is not exactly a new thing. RT itself was not really censored either (not in the way specific information is outright illegal in Russia for example) - you can still go to the source if you really want to. (See the comment below about domain blocking though) They're just forbidden from using the national broadcast, since that was always controlled by various orgs. In most EU countries you get in trouble for lying in adverts, (https://www.citizensinformation.ie/en/consumer/consumer_laws...) so I'm not surprised Russian-gov-masquerading-as-news got affected too.
