i mean if Roblox is any indication, Valve will probably bend the knee sooner or later. government scrutiny is obliging them to make changes and actually do even basic moderation over there:

The fast-growing children’s gaming platform Roblox is to hand parents greater oversight of their children’s activity and restrict the youngest users from the more violent, crude and scary content after warnings about child grooming, exploitation and sharing of indecent images.

The moves comes after a short-seller last month alleged it had found child sexual abuse content, sex games, violent content and abusive speech on the site. In the UK, Peter Kyle, the secretary of state for science and technology, told parliament: “I expect that company to do better in protecting service users, particularly children.”
