If they chose to oppose the law, maybe it tells us something, don't you think?
They don't technically need to have all the "85 rouble party" crowd to do the voting before deciding anything. It's not how wikipedia works.
Besides I don't understand what wikipedia did wrong.
About Wikipedia. Do you still remember the SOPA blackout day? Everybody was warned about upcoming blackout a few weeks beforehand, and most importantly, pretty much everyone supported the blackout, thus reaching the consensus. http://en.wikipedia.org/wiki/Wikipedia:Consensus
Today, Russian Wiki is closed. The decision was taken yesterday by a bunch of admins, who started a poll, without any warning and without anyone prepared. It is a violation of consensus rules as described in the link above: "Consensus ... nor is it the result of a vote."
Admins' actions today are a blatant violation of these rules by Coordinated actions, Meatpuppetry and are biased in general: http://en.wikipedia.org/wiki/Wikipedia:False_consensus
