I guess some of the reasons are that Sidewalk is:
- For a product that was already owned and did not need it until now
- Activated by default, as optional opt-out instead of opt-in
- For a product that was already owned and did not need it until now

I think it comes down to trust and a track record of commitment to privacy.
Also IMO apple handled the PR for airtags very well.
Find My is also opt-out instead of opt-in
The sheer fact of asking the user to opt-in automatically decreases opt-in rate a lot (like a LOT), even if that tech is super good. It is way easier to dismiss a dialog than to think what it even does.
