The thing that sticks out to me is:
We are adding a non-discouragement clause for sellers that provides:
In representations to your customers or in public communications, you agree not to mischaracterize PayPal as a payment method. At all of your points of sale (in whatever form), you agree not to try to dissuade or inhibit your customers from using PayPal; and, if you enable your customers to pay you with PayPal, you agree to treat PayPal’s payment mark at least at par with other payment methods offered.
Seems like it will have widespread implications. I'm seen a lot of places that accept donations which eg. accept PayPal but encourage bitcoin.
