As if in Bitcoin all nodes were real. Just a few months ago you basically had somebody set up 500 Amazon hosting BTC nodes, that were shut down a few weeks later since the free trial expired.
But at least DASH does subsidize people to run free nodes, so people could run them if they wanted to, and they have the financial support to do so.
Sybil is an attack vector against any crypto not just Dash, and I think Bitcoin will be the first target, because miners are already doing nefarious activities, like the backdoor meetings in Hong Kong or whatever.
I would not trust them the least, and they have the resources to mount a Sybil attack.
Yeah sure it is, but your missing the point completely with dash. A Sybil attacker in Bitcoin does not have much power at all - they still would need hashrate to do anything.
With dash, there is the economic fee of locking 1k dash for becoming a node representing quasi-stake. This fee is so trivial, especially to actors who were able to acquire a large amount of these tokens for "free". The low expenditure of value required coupled with the power of masternodes is absolutely ripe for masternode collusion and centralization.
