All I care about is whether this is opt-in and whether I can decide to not give then that data.

Other than that, Google being able to process more data about their own platform than others, is something to be expected.

Agreed, but there’s a lot to say about what’s the default and how you are supposed to opt-out.

If Google is artificially inflating opt-out costs for the user, then that’s something to watch for.
