We don't but I'd guess that the corporations behind media content and paid applications do and maybe some of the more average users as well.

I'd be perfectly happy with a switch to void the warranty and enable platform hacker mode. Just like for example how archos does it - they offer the tools for you to enable booting your own stuff on their devices but using those will watermark the device and effectively void the warranty (and remove the ability to play drm'd media). Anyway, the end-game is that I'm able to hack on it and they don't need to care if I manage to break it while hacking. win - win.
