If anything, YouTube search in Russian context is extremely West-biased. It's impossible to find any original source of Putin saying anything, for example. Yesterday he was talking about Zelensky not being legitimate. The search results are literally: Radio Liberty, some Azerbajani channel, Ukrainian channel called FREEДОМ - obvious pro-western vibes, DW, Ukrainian UNIAN, BBC etc. It's one thing if they were blocking these and only showing goverment propaganda, but it's actually the other way around.
