Apple has no significant ad business, aside from the simple App Store ads, and they said they relegated the continuous eye tracking to a separate secure system layer that apps get no regular access to right in the announcement presentation, so I really see no reason to throw Apple in the same group with Meta at all.

With closed source judgement mostly only depends on trust anyway.

I find this type of ideologic engagement with technology disingenuous overall. I either need to design and build things myself, stop consuming, or respect the work other people put in to make things I ultimately want or need.
