Valve isn't like most USA corporations, they're private and generally a lot better.

As an indie developer, Valve has helped me a lot. I have my game on Switch, Xbox One, Epic, and Steam, and Steam is by far the most revenue, and was the first platform that accepted my game. They make it so easy for indie devs to ship games - yeah the downside is they get a lot of low effort submissions, but the user rating system takes care of that (mostly). And they're adding more warnings for gamers about what games have AI generated content/art.

I've seen this happen for people behind VPNs or using public access points (coffee shops, schools, etc). Valve has to do this to prevent spammers, and the sad part is a lot of real users get hit too. But before they did there was a lot more spam user accounts in the steam forums and messaging users, usually scams. If you still want to create an account and can't get past the captcha send me a private message and I can help you out with it.

I don't love Valve, as they're just a company at the end of the day, but they have done a lot of positive things for Linux gaming and the indie developer scene. Especially for linux graphics drivers.
