it was the only place to get actual unspun news about the genocide in gaza, which is so heavily censored in the west that a couple livestreams threatens the whole house of cards. obviously the chinese have their own censorship but if your in the west your trying to escape western propaganda not chinese propaganda
same reason why chinese kids flock to discord/other services. though from what i hear chinese doesn't really care so much if you know/speak about X internal-propaganda subject, just long as you don't "agitate" or try to orginize against it.
