So happy I deleted my account with them 5 years ago after going throught their laughably bad customer protection (the only reason I had them to begin with, I had figured it was a good idea to have a buffer between merchants and my CC)
In the end, it was perfect because, as they refused to help, I went straight to the credit card to reverse the fraudulent charge and closed all accounts with PayPal... Then I get a whiny email from them when the CC took the funds and left them holding the bag... Sweet minor victory
The difference between selling your data and selling ads, is that only you can use your data. This is PayPal building a moat around its user private data so only they can use it.
