<1MB is also relatively easy to reach with swiftui apps. I had two fully working ones in the app store below 1MB. They are removed now since I didnt pay the yearly 100€

Do you need to pay the license to keep your apps in store? Or did they deprecate some APIs and therefore removed your apps?

Honestly wild if you need to upkeep the license just to have it in store once it is published.

Yes. I have a bike helmet with integrated cameras. The company (Cyclevision) that made it is gone. So no Apple account. So no app for my helmet anymore.

You could check if consumerrights.wiki already has a page on that company and if not create one. It's a great resource that will also be used to justify demands for changes to the DMCA.

This is yet another example of why open bootloaders to allow alternative firmwares for all gadgets must become legally required. Stuff turning into eWaste (or at least losing what some folks would likely call major functionality) because the creators went out of business and the gadget was locked down is a disaster for both the planet and for the concept that you actually own the stuff you buy.
