Why do you need to pay $25 in order to share code with your friends?
Why can't someone wipe the phone's storage clean and install their own version of Android, or some other OS?
Think back to the days before "smartphones", when your smallest computer was your laptop. Imagine if you had to pay Microsoft to be able to share a program you wrote with anyone else. Or if MS made it infeasible to remove Windows without making the laptop unusable.
