Not just paypal.....
Same thing is happening all over. With the decrease in sales causing declining revenue, increased bad debt and reduced EBIDA, many companies will try to cut cost and increase earnings by eliminating staff and adding fees or price increases to their existing customer base to increase the revenue without adding cost. It can also turn into a vicious cycle, raising the pricing or adding fees can cost them business and revenue as well so there goes the need to find a way to increase the revenue again.
