> Can't speak for Google's case - but Apple certainly goes to great pains to make it clear they don't collect location data on users - it's left on the user's device.

This is not true at all - as the researcher from Trinity College found out a bit of time ago, Apple collects people location data even if they're not logged into the Apple account: https://arstechnica.com/gadgets/2021/03/android-sends-20x-mo...

It's very clearly marked as being collected, so I'm not sure why this myth of Apple not collecting data is being perpetuated. It's seriously misleading actual iOS users about their privacy.
