I have no problem with lockin to specific app stores, consoles that only run approved games etc. A company can sell what they like; it's their product
... but ... once purchased the owner should be free to do what they like with it. Jailbreak, hack, whatever. It's their physical device to do with what they like. Sure, this may not suit some business models (like consoles sold at a loss) but too bad. Those companies are free to make hacking/jailbreaking said device as dificult as they like, but if someone can bypass that then good. I don't believe the goventment should be involved at all, on either side
