My extremely Baby's First Monopoly take is that whatever your feelings about specific aspects of Steam's service, or Valve in general, no individual company should exert this much power over the fortunes and overall culture of an artform. As such, I welcome efforts such as Wolfire's to challenge Valve and Steam, even if I may not agree with the detail of the suit in question.

What a stupid take. Valve isn't doing anything anti competitive, they just provide an objectively better service which is why everyone uses it. Anyone can put their game up on Steam, Gog, Epic, Uplay, and Origin at the same time. Valve doesn't own the space, and tbh we're probably getting the best deal we can get with them being the top dog, cuz you know Microsoft and the like would never treat us that well.

The closest thing I can think of wrt competitive rules is their price parity rule, where if you sell your steam keys (note that. not epic or uplay, just steam.) yourself, the price can't be noticeably lower (or a sale can't happen) without a comparable discount/sale on Steam within a reasonable timeframe.
