A good historical example of this would be the Teamsters joining in coalition with the MLK-era civil rights movement. Are you saying this is bad collusion?
In general, collusion is “secret or illegal cooperation or conspiracy, especially in order to cheat or deceive others” (Google dictionary). When the Teamsters joined in coalition with the MLK-era civil rights movement, this was neither secret, nor illegal, nor intended to cheat or deceive others. So it was not collusion.
In the opening post, the term “collusion” presumably comes from Vitalik’s article: Quadratic Payments: A Primer.
Collusion is also tricky. If we can’t prevent people from selling their votes, the mechanisms once again collapse into one-dollar-one-vote. We don’t just need votes to be anonymous and private (while still making the final result provable and public); we need votes to be so private that even the person who made the vote can’t prove to anyone else what they voted for.
If two people are trading votes in a Vitalik’s Quadratic Voting, they are bypassing the mechanisms to make votes anonymous, private, and unprovable, which are the same mechanisms that are intended to prevent the collusion of selling votes. I don’t know if Vitalik intended for vote trading to be illegal under QV, but that’s my interpretation.
