Looking just at location… Apple is actually better at location tracking precision than Google, and you can’t turn it off (even powering off your phone doesn’t shut it off). Disabling location services doesn’t prevent the data collection by Apple, it only blocks apps from using it.
Apple is probably better at not sharing your data with others than Goolge, but that’s a position of faith, not fact. If you trust Apple and are diligent about blocking location access to 3rd party apps, it’s better. But you should expect that if you’re giving location access to a free app (like Google maps, a weather app, a ride share app, a streaming app, etc.), you can bet they are selling your location data.
Agentic OS is a buzzword that’s meant to imply that the OS is (or has) an AI agent doing useful things for you in the background without you explicitly asking it to do those things (ie an agent working for you). For an agent to be useful, (they say) it has to know and learn everything it can about you, your life, your friends, activities, contacts, work, and so on.
The tradeoff is pretty extreme though. Everything you do on the PC is watched, analyzed, catalogued, and retained by MIcrosoft (and possibly whoever they choose to share the info with, which is likely every government that asks). The features that do this are generically called client-side scanning and Microsoft has a few specific variants you can read about called Copilot Recall, and Copilot Vision.
