Perhaps this is in anticipation of a new service, but this isn't really applicable to the typical sale of content, since you don't ever "provide" PayPal with content or "post" content using PayPal's services in those cases. PayPal is not a middleman in the way Apple or Steam are.
If it's not, I doubt that this is actually lawful in Europe
