on ebay again

I notice it says add 4% if paying by paypal.......
E-bay have banned people from making these extra charges..

Not my item and i did not knwo ebay banned charging but I cant see why. If banks charged 5 % to bank a cheque I bet people would start charging is it because ebay own paypal.
