Privacy is something you give up for all online software. I give up privacy to use YouTube, search engines, Hacker News and even DNS. Unless you can show me the source code for Apple's implementation, I daresay they're forcing you to give up a modicum of privacy too. Same goes for OpenAI's servers, for that matter.

Mostly I dog on Apple and Microsoft because both companies didn't even attempt to compete. They ignored machine learning when it was taking off (FAIR/BERT era), refused to ship complex GPU designs instead of NPUs though it was the only thing working (eg. Nvidia vs everyone else), and they continue to lag behind all their peers in local model development. The most impressive contribution either company makes to Open Source AI is the support they write for Tensorflow and Pytorch - neither of which they even own. If you erased every contribution that Apple and Microsoft made to AI research, the entire field could pick up where it left off tomorrow.

Google's got problems, but AI is something they are far-and-away better at than their contemporaries. It is just Google and Facebook at this echelon, which is embarrassing but frankly expected given how stagnant and anticompetitive Apple and Microsoft's business models have become.
