Why are streamers allowed to get away with everything?

Of all the games I've played, Siege probably has the worst streamer culture out there. Most of them are blatantly smurfing, being toxic and baiting reactions from their teammates so that they can farm content. It's impossible to find a streamer who's playing at their own level and shows basic human decency to the other players, and I was positively shocked watching the invitational because I was watching Siege being played, not some streamer playing half-asleep and content baiting for 80% of the game.

How does the community allow this? Ubisoft themselves banned many streamers for using smurfs and botted accounts so that they can deliberately play on an elo way below theirs but they all just pulled out the victim card saying "Damn evil overlords of Ubisoft banned my account because I was too good" and the community just let it slide.
