I think the only portion of the community trying (and succeeding) at creating a deadlock is the large voting block of the Korean community. But that overall speaks to the uphill battle that organic witness voting has versus the Tron sock puppets. The spread of voting on genuine Steem witnesses is much larger because it behaves like an American political election where a third party candidate can draw votes from one side or the other, possibly swaying the election in favor of the opponent most against their own views. If everyone voted on 19 more witnesses at the same levels Blocktrades is getting, the Steem community would reclaim every spot, but some folks remain true to voting on a wider variety of original witnesses. The “Tron 20” has the advantage that it can move in lockstep as they’re really just one account with a small handful of voters.
