This is, admittedly, not 100% a reply to any of the ancestors of this post, but, well, it's definitely an opportune time. Labeling all disagreement as "sock puppetry" is already a popular rhetorical dodge and this news is only going to make that worse. If you want real free discourse, you need real diversity of viewpoints and you need to foster that diversity, not insist on conformity.
If the only place that diversity is coming from truly is sock puppets, well, I would consider that a condemnation of the community in question. (And make sure you read that sentence very carefully before replying; it doesn't say "we should trust the sock puppets" (hardly!). It means that there should be diversity in the community, before we add in any viewpoints, right or wrong, expressed by sock puppets.)
But the problem is that on the specifics, a few topics are indeed unanimous. You won't get diversity on those, and this is not a problem.
unfortunately as even my own worst paranoia was not predictive enough, paranoia that has had me laughed at to my face and behind my back, given what's come out: it's very hard for me to react reasonably.
so people with a different bias to myself or others can greatly contribute to such discussions.
