Especially after people paying so much money for the devices, it's ludicrous that they are not allowed to make their own decisions and install what they want. Ownership, user rights, and privacy have been kicked in the face. If you can not install whatever software that you want, then people should be signing only rental agreements.
It is also more the reason to push Linux smartphones[1]. Android is not doing anything special, that people could not get or create for Linux phones.
