Earlier quoted context omitted.
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
Isn't it the same with airtags? Your iphone will forward data about other people's airtags as long as you have upgraded to the latest ios. You can opt-out, but you need to know about it first. Same deal I think with sidewalk.
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.
