I agree. Daniel Larimer's blasé response to this concern was rather disappointing.
"Dragomauri, [Jun 7, 2017, 2:51:38 PM]: Daniel, aren't you worried that the 21 masternode/full nodes could be blacklisted by ISPs? Could EOS work on tor or i2p?
Daniel: neither has sufficient bandwidth
Daniel: there are datacenters around the world"
A state level actor could easily buy out or put the squeeze on 21 individuals, if they were known. Heck, even relatively smalltime criminal enterprises, such as carding rings, botnet operators, and ponzi schemers could probably put up enough money to cripple the network.
