PayPal has been trying hard to change this image. David Marcus, who took the helm, has been shifting focus on customer satisfaction. Here is an interesting article on David Marcus:

The MailPile thing happened at the beginning of this month - the fact that this can happen at all, and, as usual, nothing was fixed until that bad press started to roll in, points to a systemic problem and culture at Paypal that just changing a CEO isn't going to fix in a reasonable amount of time.
as far as topic at hand is concerned, MR from Braintree will be working closely with DM and directly. So expect only good things. Buying Braintree is a business play. (Just check out their numbers and clientele). PayPal can try to get clients like AirBnB or Uber but those startups would try every other bush before PayPal.
Hope this helps
P.S: I work for PayPal and probably one of the strong proponents of it. The above opinions are purely mine. and No i have not been canned or put in a timeout box.. yet!
