These are good points all, I basically agree. However, if one understood the culture of Open Source and crowdfunding, it would be relatively easy to see that Mailpile is a pretty low risk for outright disappearance and chargebacks. Also, a project like MP has serious PR risk for Paypal being such dicks. I suspect someone in-the-know at Paypal made this argument, and to their credit they backed down quickly in the face of potential Twitter disaster.
