All valid points, but I am certainly a lot less skeptical towards Apple given their income is from hardware and cloud services, not data processing. Yeah – they are legally obliged to pre-scan all content before encryption and compare it to known databases of illegal images etc., but their business model is about selling expensive physical products.

On the other hand, Google's entire business model is around harvesting and selling data to third parties, and services such as Chrome, Chromebooks, Pixels etc. are to extend the capacity to gather data to sell more of it and train their AI with it so they can sell that too.

If a normal person who values convenience wants to improve their privacy, I would personally recommend Apple over Android or Microsoft any day. iOS is also notoriously difficult to breach, especially because updates are often forced, meaning most users are on a similar, recent version of the software. You can't say the same about Android or Microsoft, which leaves these devices vulnerable to known exploits.
