It's much easier to pretend that this is the case when the file system isn't verifying it.

Checksumming would probably expose problems that would otherwise go unnoticed by users or be blamed on computer gremlins. It's hard to say if doing the "correct" thing here would improve the subjective user experience. Maybe putting on airs of infallibility is the more profitable route.

Good point. Going by the tone of Apple engineers' response, it sure does sound like they are going for plausible deniability.
