PayPal's customers are the people who use it. You, as a merchant, are not a customer of theirs, but a necessary evil to keep the customers coming. PayPal's customers love it. PayPal's merchants don't like it because PayPal has fraud prevention methods that are opaque and hamfistedly applied. That's a fine complaint, but this breathless "for the sake of the world don't ever use PayPal" garbage is pretty ridiculous.
If you want to do anything beyond selling tangible goods or simple subscriptions, you should probably reevaluate using PayPal to do that. PayPal isn't the best product for everything, and frankly, I'm sick of every merchant doing some crazy scheme (seriously, "give us money and maybe we'll send you a gift of some unspecified value in the future"? can you fucking spell "chargeback"?) bitching and moaning into the HN echo chamber whenever PayPal tells them to stop that.
