Yes, before there was electronic bookkeeping businesses hauled stacks of paper to their accountant. This is standard business practice since literally centuries.
If they want to send you a letter, they have to give your data to the postal service. Again, no consent needed.
This is legal because our whole economy is based on devision of labor. Privacy laws account for that.
Maybe you are referring to required data.
I can buy some bread and the store does not need my ID for accounting purposes, so not sure what exceptional stores or gym need to send a copy of my ID and my activities to their accountant.
My problem is with the 100+ partners that are OBVIOUSLy not partners and not required to have my data.
Ok, now what's the difference between sharing "1 bread sold" (with no identifying information about the customer) with a third-party and "1 page visited" (with no identifying information about the visitor) with a third-party?
"1 page visited" (with no identifying information about the visitor) with a third-party?
False equivalence, no online stalking company actually works like that (that would require a server-side hook). They all make the visitor go to the third party's desk and increase the tally themselves (via http request), giving the tracker company access to all the contact details of the visitor.
If they want to send you a letter, they have to give your data to the postal service. Again, no consent needed.
