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.
That's basically all corporate entities. They're not beholden to the workers, the consumers, or the general public and instead answer to people generally trying to milk everything as hard as possible.
Not gonna defend corporations here, but valve isnt public. They are privately owned by the bosses and employees, valve has one of the lowest turnover rates in the industry. It is quite difficult to get a job there for that reason. So they are actually quite beholden to their workers.
Valve wouldn't exist at it is if it was public and might not exist as it is if it wasn't for Newell (and I say that as a person that's very critical of Valve, they're still very far from how bad they could be considering their position)
