I think there's a difference between gathering information that's necessary for the service at hand (giving your IP address to a server, or your current location to a cell phone network) and milking the user for all identifying information that can be gathered (asking for the user's gender to create a shop account, browser fingerprinting by scanning plugins and canvas hashing, etc).

Regardless, how is breaking up Google going to stop such tracking?

I've asked this question twice now. We can't just break up companies because they collect data. That's not anti-trust.

Well that's a question for SomeOldThrow, I don't know how breaking up Google would help either.

You’d need something like the GDPR I imagine.

While tracking and anti-trust are only loosely coupled, both are symptoms of an anti-social company.
