Under the guise of "security" you can achieve a lot. It's also easy to put people in the corner with this because anyone who does this is automatically against security.
And also here on this topic you can read (from the usual suspects). People who repair phones find crutches. Used batteries are by definition dangerous.
Yes, people are well-knit because they even go so far as to change or disable the functionality of their eyes. How can you argue against that, they don't listen because they know all that well.
As for security, Apple certainly has complete control over its parts in the meantime, and everyone has done it themselves (those parts chips are really useful, with the next update you can cripple any unofficial fixes again).
Nice for second hand markets, you can read the comments here (again from the usual suspects) because you can now see that there was 'interference' in the device. For example, as a company you are forcing original repairs because no one wants to do manual work.
Whoever connects with Rosman will usually get -1, the usual suspects do so because criticism is out of the question. They defend a brand as if it's their own identity, you can't fight it, you don't even have to do it. Leave them alone, someday they will even think it's enough. Consumers should never accept such restrictions, especially when restrictions are imposed ONLY they bought a device.
