Well huge fees that paypal charge for money transfer is one of the reasons why bitcoin emerge to be better as payment mechanism. I see the reason why Mr Harris is so against bitcoin because they see bitcoin as a rival to their business.
You're absolutely right! As a frequent PayPal user, I cannot even tell you how much money I lost because of their exorbitant transfer and conversion fees! It's only natural for the competitors to feel threatened by a payment system that is cheaper, more secure and way more efficient.
