I agree with a lot of your comments, but just FYI, you can do a couple of those things:

You do need a Mac, but you can build FOSS apps and deploy them to your own iPhone, iPad, or Apple TV with a free developer account. You only need the paid license to distribute them to others.

There have been apps that support this for a while, but this is now a built-in iOS/macOS feature called "Sidecar".

I am afraid I also need to pay 100$ for the license to use certain features because if an app uses them I cannot even compile.

Recently I tried to compile blink[0] without a paid account and failed miserably.

Yes they also did a great job with sidecar which will only work if you at least own a recent mac. Also it does not work with the iPad Air 2 because they decided it is too old. It is the same story again: Apple softly forcing it's customers to upgrade - nice experience...
