I have to respond to your point, though. Whether 30% cut is excessive depends on whether devs feel like they are getting a good deal. As far as I can tell, game developers don't seem to complain about Steam cut very much, it seems like the value you get is worth it.

For example, this thread https://www.reddit.com/r/Steam/comments/10wvgoo/do_you_think... seems like majority is positive about it, even though people debate. When Apple tax is brought up, there's almost never even a discussion there, it's pretty universally hated.

Apple seems to have almost adveserial relationship to its developers. I deploy to App Store and I feel like I'm getting screwed. Even compared to Google, which takes the same cut, but does bahave a lot more nicely to its developers.

I'm not judging that, it just seems to contradict the "But Steam shows us another model..." sentence, so I'm trying to make sense of that.
