it's a good thing. paypal is not the end goal---it's a means to an ends.
sure, when the paypals and fidelitys and jpmorgans of the world get involved, it leaves a sour taste in our mouths. that's understandable. but the silver lining is that they are legitimizing bitcoin in ways the community could never do on our own. people look to institutions like this as authorities on money. if they expose their hundreds of millions of customers to bitcoin, a chunk of those customers are not only going to invest in bitcoin through their platforms, but they will eventually become real bitcoin users. that's the road to mass adoption right there.
