Since privacy is a key differentiator for them (huge financial incentives to actually deliver and not just pay lip service), and there are significant penalties waiting for them if they are lying about protecting privacy (as well as plenty of people who would love to call them out on it), Apple is probably the most trustworthy of any organization if you care about privacy. Also you can keep your data local with Apple hardware - it's encrypted and only available to your hardware - obviously a lot of the functionality they profiled today doesn't work if you take that stance, but it is an option.

Which? It's still all closed source and tivoized, so you're still taking their word for it. At most they'd have to bullshit together some whitepaper about what they claim to do.

The same "significant" penalties that were applied to Equifax?
> Also you can keep your data local with Apple hardware - it's encrypted and only available to your hardware
They already have several white papers about how they treat privacy - dunno why you would assume they are bullshit right off the bat.
As for validating their claims I don't need source code for that. There are enough people (like you, apparently) that have an axe to grind that would be more than happy to point out any malfeasance - for me that's far more valuable than having source code available.
