Wages are also subject to change based on performance or company profits.
But what I mean is that the company and the worker have the same interests in some way. Everyone wants to make money to pay the bills. Companies are no charities and your work isn't either. If you dislike your relationship with the company, you can just resign that relationship any time. But one thing will never change: the worker will only do the work required from him and the company will only pay the wage required from them. There is nothing evil about that. It's human nature for the past 20.000 years.
I gave Epic's store a chance but even after all this time it's still shit and very far from feature parity with Epic. There's not even proper reviews. No big-picture equivalent. No good out-of-the-box Linux support. No Steam-Deck. The list is very very long. Until Epic starts delivering, the 30% cut Valve takes is more than justified.
