It's hard for me to feel scared about the control a company has over a product I can choose not to buy. Of course I do think you should have every right to jailbreak/root your device and vendors should have every right to cease updating or warranty repairs in return.
Personally what I find scarier is courts and other govt institution deciding what products companies are allowed to make or sell me.
