Someone built a location API or crypto API or whatever so that apps can use that data.

If there is a permission that violates the trust between the system and an app using aforementioned APIs all bets are off. This is similar to why rooted devices are bad for security.

All bets are off for the owner of the device or the author of an app? Bad for who's security?

As a device owner and user I don't care for DRM style 'security' protecting app authors from me running my software on my computer.
