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.)
Not that I condone capitalism, or socialism, or communism, or fascism, or any ism for that matter. Ism's in my opinion are not good. A person should not believe in an ism, he should believe in himself.
But a private company, at this point, can arguably affect the greater good just as much as a public company. The rich are getting richer, and the corporate model is just there to support that transfer of wealth.
