"If it's my device, I should be able to do whatever I want with it"
What's the problem? If you want freedom, then buy it without discount. "Maybe you would buy a lawn mower" No. And I never see people using lawn mower. If not count workers of parks. "only the manufacter can repair it" This is different case. You're not have any choice. "resist doing that is the possibility of losing the warranty" Very funny. Why I need to repair it myself, if I have warranty?
