That’s just not true. They’re seeking profit by attempting to be the best place to spend your money. Epic would love for Valve to charge users monthly for Steam, but they don’t, because it would just drive people away from Steam. They stand to make more money by doing what they’re doing. This is not a public versus private thing. Arguably the negative that comes along with public companies is that there are more short term incentives at the expense of long term profit, but they’re both doing what they do for profit.
