It is a little bit of both, in my opinion. Sure, it is an advantage in the sense that they have even less control over the network. But, it's also a disadvantage, because it cannot let itself spread in the same variance as with Bitcoin.

Merchants and customers usually don't care about their privacy, whereas the government cares more than anyone about the merchants' and customers' privacy. So, there's not enough resistance from both sides. You can argue the same about Bitcoin, but the difference is that it's surveilled by the governments (and even that way, it's been attacked constantly, imagine).
