I would argue Valve already lost its way, it's just that their enshittification took the form of gambling-adjacent lootboxes. People forget that TF2 was one of the first western games to add lootboxes, way before Overwatch even existed. Even Portal 2 had them crowbarred into the co-op mode for reasons. That's why they stopped[1] shipping single-player experiences.

CS:GO is the worst offender; to the point where there's third-party gambling[0] sites to gamble cosmetic gun skins with, that specifically cater to children. Basically all of CS:GO's pro scene is sponsored by it.

[0] The skin gambling sites are not officially condoned by Valve, but they absolutely do not do shit to try and stop it.

[1] Half-Life: Alyx notwithstanding
