He promotes gambling, with the knowledge that children are involved. He has facilitated using Steam's market dominance to persue anti-competitive practices, like not allowing games to be sold at a lower price anywhere else. There's more too. Yeah, he's not exactly good.
I give zero fucks that he could be worse. If that's your only argument, your ethics are horrible. Someone being worse does nothing to make your actions better.
Yeah he could play nice to make people like you happy and go out of business or be bought out by someone worse.
Oh yeah, one of the most profitable companies per employee in the world is surely going to go out of business if they don't persue anti-consumer practices! Think of the poor billionaires! If they don't do these things, they will have slightly less money!
What I expect from him is to stop leveraging their market dominance to do monopolistic actions. I expect them to compete fairly, not abuse their position to create barriers to competition. I expect them to take a look at their practice of promoting gambling and change to something less manipulative, particularly if they know children are involved (but adults too). These are the bare fucking minimum of what we should be asking for. What do you expect? You expect to be taken advantage of and abused?
