Something like eBay accepting bitcoin would have been like a Bonsai of global adoption. The degree of global spread eBay has would have great for bitcoin advertisement. Hopefully someday they do integrate bitcoin.
if they are cutting the bridge with paypal, which was going to use bitcoin, i don't think that they have any interest in using bitcoin, they also said why, they thing that it does not offer a customers protection
i believe his is the same reason why amazon will not accept it for now, they are all waiting to find a way to make it more secure for users
