I think the point being conveyed is that, the internet or www was easily accessible to people who could go on to modify things to suit their own end. Yes, you can use bitcoin as is, thanks to a number of available software choices. But it is difficult to do anything else with it.

However, at this point I can only see it as a currency. So I can't say if the second point is even applicable here.

Maybe the reference is to the underlying blockchain, the effort required to understand it, and consequently customize it like people did with the older web technologies.
