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.
It's done some good stuff for the industry and even contributed to some bit FOSS projects. But business is still business.
They seem to have a high ownership, consensus driven organizational structure. The only time I'm aware the consensus model was violated was when Gabe overruled a veto to ship Steam with half life 2.
It's very interesting to me because it seems to operate similarly to a lot of anarchist shit I've been involved in, but at a highly effective level. And they make oodles of money.
