I find the anti-telemetry attitude honestly kind of confusing. I mean, you know that the shops you go to know what products you're buying from them, right?

If you're transacting with someone, it's not possible to hide that transaction from them. Of course you should have the right to have that…
Web tracking is different in that it's ongoing tracking of behaviour. When I buy something from a shop, that's the end of their knowledge: the shop has no idea what I use it for.
