I read this as saying that it wasn't Steam's decision, but that's actually not clear. Does anyone know more about that?

I know that some Valve multiplayer games like TF2 are getting bombed by bots right now (and have been all year) and have speculated about who could be behind simultaneously running thousands of instances of bots for months, that have paid accounts running them (as in they have microtransactions in the game) and wondered if it's a state actor, because that's a lot for a small group of people to do just for trolling. I suspect China is pissed at Valve because they have no investors (unlike Epic, Riot, Blizzard, etc., that are part-owned by China and given in to them) and generally have never buckled to pressure, yet remain a top company, valued at billions.
