To play devil's advocate.. While you may trust them more, you can't deny they have had many significant software security issues of late. How could consumers trust the security of their chips?
The admin access without a password bug -- fixed in 24 hours, and it still required physical access to a machine.

I feel like Apple actually cares deeply about privacy. Look at Tim Cook's personal life for example -- extremely private person -- someone, given his life story, who probably appreciates privacy more than most.
No company is perfect and no company should get a free pass for negligence, but I think Apple has earned the benefit of the doubt.
OP raised a valid argument - Apple's QC has been crap lately and trending downwards. There's a lot of feedback out on the net to support that line of thinking.

Hardware, though, you've got nothing. Where have they dropped the ball on their chips?
When Apple's custom CPU has its first F00F-type bug then we'll see how they handle a real issue.
