I can't help but wonder how many developers are now considering whether iOS support for PWAs is good enough to sidestep this crap entirely. Tim Cook really needs to learn the definition of the word "symbiosis", because a smartphone with no third-party software is barely worth anything.
I expect that in a few years they'll say that their "Core technology fee" doesn't actually cover the full development experience, only the "core" of their technology, i.e. the compiler, while device-specific frameworks/libraries ought to cost extra for the relationship to be "fair".
As you say, Apple have forgotten how their relationship with 3rd party developers really works. They owe their success in the mobile space to them, yet they're so quick to brush them off and have the nerve to say that actually, developers should be paying them for the privilege - it's disturbing.
>I was under the impression that devs and consumers that cared about side-loading largely already self-selected to Android.
Consumers mostly did, devs would still appreciate the feature since usually the choice isn't to make only an android nor only an iPhone app.
It's hard to make any money on a PWA.
For what it's worth, I much prefer a high-quality native app to a PWA, but Apple's treatment of developers as basically bottom feeders leaves a very sour taste in my mouth.
