What does Musk have to do with the modern Paypal, that is generally disliked. The primary issues with Paypal come from the freezing of accounts, that doesn't affect the majority of users. It mostly only has effects for business with spiky sales that may appear fraudulent.
But the current view of PayPal is different from the historical view. PayPal was a brilliant service through the end of the 90's and early-00's, while Musk was involved. You can't retroactively apply the dislike the service has generated since their paths diverged. And even then I would contribute much more of the social impact to Thiel.
