Why wouldn't an attacker be able to counter-sybil-attack that effort?

I'll remind everyone that Bitcoin Core does not condone participation in
network attacks to push controversial protcol changes through. I also
checked with Adam Back, who confirmed Blockstream as a company shares
For those readers unfamiliar with Sybil attacks, basically what the
above does is prevents nodes from being able to finding peers with
accurate information about what blockchains exist - the above can be
used to prevent nodes from learning about the longest chain for
instance, or the existance of substantial support for a minority chain.
This is why we've advocated giving users sufficient time to actively
opt-in to protocol changes.
