You keep repeating this disingenuous argument. If you don't want to root your phone, don't root it. If you don't want your kids to be able to root their phones, don't pretend like you aren't taking away their choice.
If you don't want rival stores with lax standards, don't install them. Just don't keep telling people who want to be given a choice that they're somehow "taking your choice away from you".
If you want to be in prison, go ahead, but don't pretend that having the option to leave is somehow "taking your choice away".
