On the surface it sounds good, but at $150k it's virtually being swept under the rug.
I won't harp on it too much, but credit card agreements weren't designed to accomodate quasi-cash and barter transactions like paypal and dnf$. Competition and aggessive lawmakers have turned credit cards into very consumer friendly payment vehicles. Paypal has no serious competition and has managed to avoid regulation so far... it stands to reason that customers will continue to have difficulty with disputes for the foreseeable future.
