I'm surprised you haven't been flagged or just a dead comment. Any signals that Apple is not pure evil for taking 30% is not part of the echo chamber group think around here. People never want to admit that it costs money to retail your product no matter where it is. In the physical world, there's manufacturing and delivery costs. Getting shelf space at a retailer takes a lot of negotiating where you have very very little room to bargain. Retailers will even force you to buy back unsold product. Yes, software doesn't have all of that but have their own nuances. A lot of indie game devs don't have time/skill/want to do a lot of what an app store can do. Expecting to get all of that for free because it is software is just not sane. If you are self-hosting all of it, it will not be free as you will be paying for payment processors and a hell of lot more in attracting eyeballs.
The problem with Apple is not the 30% cut, it's that you're not allowed to use other app stores or install apps without their store.
