I'm really glad I stumbled on this post @rycharde, it answered a lot of questions that have been on mind, of which the most foremost is "Are social networks and blockchain really decentralized?".
I'm fairly new to the blurt platform and I observed that what we have here is a more "decentralized system" that what we have in other graphene social platforms. The most notable being the Curation return curve is around 50% of what your vote gave to the post you voted. This is the same regardless of whether you are a whale or not. And most importantly, the removal of the downvote button which was mostly used as a tool to exert power on weaker accounts and young communities that doesn't agree to a whale's terms, or simply one a whale doesn't like.
But we can't say decentralization (of blockchain and of network) has been achieved perfectly in the blurt system, as the system is not yet perfect and their are loop holes such as the ones you mentioned in this post. The most prominent of which is the unequal worth of witness vote, which is judged based on the worth of an account. Although I don't know so much about the story, but I know the exploitation of this flaw is what forced the initiation of forking of steemit, and creation of other platforms like blurt, hive, serey e.t.c.
Concerning this, this is a question of investment and the safety of the blockchain. It is understandable that every heavy investor will like to be in control in the decision makings that can influence the profit or loss of his/her investment, as compared to little investors, they have more to lose in terms of amount. But when we consider the fact that a man's $10 may be worth to him even much more than a person with $1bn will value his $100 this brings us to the point where we need to consider the safety of the blockchain ensuring equity this time not equality.
Although, the above suggestion may sound logical, it still has a catch, as many investors won't invest in a system they won't have a level of control, more than a person who invested less, attractive to investing in.
Now, this puts us in a crazy situation. And for a growing account which depends mostly on vote from ctime and blurtbooster, as well as blurt curator and nrg, (as it's more probably to get votes from those accounts, which I believe are people's investment), it is something to worry about.
I hope the witnesses come to the best decisions concerning to this matter.
