Valve support has historically been pretty awesome. They even replaced an index controller nearly a year out of warranty. Granted their controllers have a shit switch and they break after a few hundred hours, but good on support for being bros.
It's not shareholders specifically, but management that doesn't give a shit about the company long term.
The business has a fiduciary duty to benefit the shareholders, but it doesn't have to be short term only, or at the cost of long term benefits.
Most publicly traded companies end up with leadership who are only interested in justifying their employment through the next earnings call or making sure the stock price has gone up between when they last got options and when they next vest.
Valve does good not because they don't have shareholders, but because their leadership is not gonna get fired for thinking about next year instead of next quarter. So they don't squeeze the consumers for every dime, so people stick with them, and developers stay even though their fee schedule is not the best because they have all the people.
I feel like GOG deserves at least some respect. They don't have a perfect track record, by any means, but I find them at least reliable, decent sales, have gotten some fun freebies out of them in the past.
And, hey, shopping cart. Which shouldn't be a selling point, I'm fucking flabbergasted that it came to this on any platform, but that's another point above EPIC.
I don't think they're that dumb, I can see them making their own launcher with PS+ sub to get free games or something like gamepass, but locking online play behind a paywall on PC sounds too braindead even for them, it'd be an even worse PR suicide attempt than Epic's exclusivity shenanigans.
Sony: we make so much money selling these games to a giant pc audience;
Also Sony: what if we restricted them geographically a huge amount and require them to go through extra steps so we can (???) which allows us to (??? + Harvest data)?
The chances of Valve games becoming PlayStation exclusives is pretty close to zero. The only way that would happen is if they were acquired by Sony, and hell isn't freezing over any time soon.
