I sort of get it. Every competitor, except maybe GOG, has come down hard in hyper-capitalist value-extraction mode quickly after pretending to do any good-will. For Valve, being a somewhat decent company is part of their ethos, for their competitors it's a means to an end.

I trust Valve not to screw me over, even though I know they totally could. Their own DRM is pretty weak (just put a modified DLL in the game directory and the game will launch), luckily.
