I can't think of a company that has done more to democratize banking than PayPal.
Setting up a Merchant Account can be a real pain (and I too hope PayPal improves in this regard), but I really hope the author thinks harder about the title next time before making such a generalization.
If you want to know why PayPal is not evil, try this experiment:
Go to your bank and try to open a checking account with a debit card with no minimum balance, a positive interest rate, ability to transfer money instantly without writing a check (basically a wire transfer) for free, no insufficient fund charges, no monthly fees, free online and mobile banking, etc.
PayPal offers this to everyone, regardless of how rich or poor you are. If you don't have a lot of money other banks such as WellsFargo, Bank of America, etc., could care less about you and will try and take as much as they can from you in the form of ATM charges, monthly fees, overdraft charges, etc. Of course, I may be making my own over generalization here, but suffice it to say that I don't think PayPal is evil.
