Well your want for a locked down device is restricting my freedom. Too bad.
You are literally standing in the way of progress and you're NOT more secure on iOS. If anything you're a bigger and easier to break down target.
If you work at a place where part of the job description is that you must work on devices that you refuse to accept, then you can always choose to leave that job and go somewhere else.
Don’t pretend that you don’t have a choice here.
This anti freedom nonsense must stop. The ability to side load does not make an eco system weak.
