We can look at phones and tablets, where bootloaders are locked down, to see that there is an interest in making sure that the secure bit doesn't get flipped by the user in the name of "security".

There's an incentive to disallow unauthorized software from running on your hardware platform: it forces users to go through approved channels for their software and data. If you own an App Store and services like iTunes, the financial incentives exist to ensure your users don't sideload content or use competing app/media markets.
