Except Apple does a pretty good job of keeping your data on your device. Sure, they’re no saints, but they put a lot of effort into privacy.
So why is it ok for apple to do that, and non of their vendors?

I'm not sure how that's relevant to your privacy as a user, although obviously the tags and other trackers raise concerns around abuse.

Apple can't know that it's not a legitimate communication because they don't know who you are, what device is calling for help, and who the device owner is.
And if you want to use my phone to upload a few bytes/second while I'm passing by, as long as the data isn't being stolen from an air gapped system, be my guest.
