Can think about Steam tax whatever you want, but they provide a hell of a lot more than just a half-assed store and some exposure for your games like Epic does. Don’t get me wrong, I do gratefully take the free games and I do appreciate the competition, what I want to say is that Steam doesn’t just pocket that money. They provide forums; frameworks for stuff like modding and achievements; a much better client useful beyond games they sell; subsidized hardware and support for Linux as an alternative to Windows. All of this also benefits game developers one way or another and costs money to develop and maintain. (Software) engineers are anything but cheap.
