This is just a symptom of Valve's "fuck you, we're rich" community policy. The only time they do shit is when they're in legal trouble over something. People have literally used Steam curation to harass developers, they still haven't done anything about it. You can literally report someone with a slur for a name, nothing will be done about it. In this case, I can almost guarantee nothing will be done. Steam's "community" is a shithole, so much so that even Valve gave up.
It's ridiculous how deep gambling made it into CS's culture before Valve "noticed" (lmao) it. They literally sponsored events that Valve attended, yet only now do they notify them that they're going against the Steam Subscriber Agreement.
