@okei "some people need to earn a few cents as professional chess players and lichess encourages that by promoting their streams and their lessons. Also Twitch takes most of the money from ads so streaming is really a labour of love for chess fans apart from the really big streamers who earn a little."
From your answer, I'm not sure if you've seen what Andrew Tang did to his stream, as you didn't address it. The issue I raised is that streamers like Andrew who exploit their streams to sell junk are acting in complete contradiction to the non-commercial ethics of the Lichess platform. If one agrees with Lichess' ethics, then what Andrew has done to his stream (putting up flashing ads that sell non-chess related clothing and unhealthy canned garbage) is simply wrong, and it reflects badly on Lichess and the chess community. I have no problem with streamers selling chess lessons or DVDs, but if everyone is allowed to use their streams to try to make money by selling crap then we can expect this platform to turn into the equivalent of Onlyfans.
