The EOS BP landscape has shifted dramatically in the past week, with now a majority of producers located in China, in the Chinese jurisdiction or similar.
I am personally sceptic about the concentration for location, but i don't see a problem with "the commies taking control of eos" fear that has been spreading. What is more problematic, is allegations of collusion, that have popped up in chinese media, and now spread over to the english speaking realm:

Basically this states that the exchange Huobi seems for one being a part of bp voting ring, and on top of that sells its remaining vote for the expected payout of the bp. Especially the latter is highly problematic, as it would allow those players to play the system and milk the bp reward pool and possibly any other community pool, like the worker proposal fund.

How could this solve the collusion issue?
The implicit logic in Colin's considerations, is that once there is a facility that enable holders a passive income of EOS, collusion and vote buying will be highly disincentivized. That sounds interesting, but would that even be possible, i asked myself. So i tried to do the math myself.
