> I'm a non-profit So the only thing that applies to you is the price to have access to a Mac. Since you're a nonprofit, Apple will waive your developer fee, and you wouldn't need in-app purchases anyways. Also, IIRC the cut Apple takes is 30%, not 33%, in line with the rest of their App Store policies.
Author here. That's correct - Apple waived my $99/year fee. I documented that in the post. But my post wasn't about me , it was about the hurdles involved in getting a PWA into the app store. For many people, $99/year + 30% in-app purchases + $1000+ Mac for build and testing + a few Mac Minis for CI servers ...that is a barrier.
BTW, the best solution for your case is VS App Center (https://appcenter.ms), which has a free tier and does CI/CD (on Macs) across platforms.
