The difference between RT and other broadcasters like France24 or Voice of America is that RT is a state-owned broadcaster. This means that it's funded by the Russian government, which gives it a different editorial perspective than privately-owned broadcasters. Private broadcasters are free to criticize the Russian government, while state-owned broadcasters are not. This is why Russia has banned RT in Germany, because it doesn't want its own state-owned broadcaster to be criticized by private broadcasters.
