Depends. In some sense EU companies are quite afraid of the GDPR. Privacy is used in a twisted way in that argument: if any privacy relevant data is exposed to another party, and there is any incident down the line, they fear they could be made responsible. So they to block you as a user to access your own data.

Of course, if that privacy risk came from them storing and selling your data, they happily accept that, you are right in that regard.
