In my opinion, every manufacturer of a programmable device should not be allowed to prevent the buyer from reprogramming it.

You're legally (and technically) prohibited from re-programming GPS modules, GSM modules, and probably many stuff in cars as well.
(Actually, maybe contractually when it comes to GPS modules.)
GPS et al would be non-functional if everybody could make a jammer.
(That’s not to say that app stores fall even remotely in that category.)
The only reason it's "illegal" is because they were thinking people would use it to make missiles easily - but that's already the case even with non-reprogrammable gps. And in big 2025 you can also just use drones with bombs attached to it.
