This can actually be seen as some unplanned attack on Bitcoin, if they operate like this for a long time. (The PayPal CEO said, their business model might change in the future, but we will have to wait and see if that will happen or not)
Interesting as EBay announced this week that no more EBay payment transactions will run through PayPal -- my estimate is this will be a significant impact on PayPal. Additionally EBay is requiring tax info to send to the IRS for every sell transaction someone makes on EBay for selling and tax purposes. Eek.
