No dude. These companies are several decades old and continue to make money hand over fist by exploiting their customers. They do this shit because it makes them a fuckton of money, because their users have no fucking principles or backbone and just lick boots every time they’re stepped on.
I am not an optimistic person but literally the only explanation I have for this sort of thing is altruism. That Valve is a company that simply loves its’ community and doesn’t want to exploit their customers. Nothing else makes sense.
