The HL3 memes don't even seem fair to use anymore. I don't even want to un-seriously make joke fun of them at this point. They are just genuinely doing so much for the community.
But overall Valve just seems straightforwardly less shitty towards the consumer than other major companies in their space, by a long shot.
The issue really lies in the fact that the (long-term, majority) shareholders aren't much, if at all, related to the customers or employees of the business, but first the founders, and then parties who are merely interested in rising stock prices and dividends. It feels like the solution here ought to somehow desegregate voting rights from how many shares are owned, instead of dismantling the concept of public ownership entirely. (Or, perhaps, allow the general public to proxy vote via their 401(k) index funds?)
(There's also strange situations like Google/Alphabet, which is publicly owned, but effectively does not allow shareholders to vote on anything.)
This is unquestionably, undoubtedly incorrect. It is a really low information meme that's racing around the Internet right now. If you want a contemporary counterexample take a look at NASCAR. They're also not publicly traded, they're family owned, yet they are abusive toward drivers, teams and fans, and they're gradually ruining the sport that made them rich. We know all of this because it got so bad Michael Jordan decided to sue them and there's a ton of information coming out in discovery at the moment.
The real reason Valve are being the "good guys" at the moment (not really, but yes they're doing some amazing stuff for Linux) is because they feel threatened by Windows and Microsoft, they perceive a long term competitive threat to Steam. Competition makes businesses both private and public work for your dollar. The US economy has been characterized by a decrease in competition and an increase in monopolies for decades now which is the root of many price hikes and anti-consumer practices.
