PayPal doesn't like micropayment competitors because the easiest way to do micropayments is to force users to load larger denominations in advance onto a wallet. This is bad, because this directly competes with PayPal's core offerings, and is an area where competitors can drive merchant adoption with vastly lower fees. In the macropayment land, a competitor could come in and offer 45c to process $10 instead of PayPal's 60c. No big deal. In the micropayment land, a competitor could come in and offer 10c to process $1 instead of PayPal's 33c. MUCH bigger deal.
