In this instance I don't expect any amount of voting to make a significant difference to the fact that 37.5% is an enormous and dominant share of stake.

How does that math work out? Please enlighten me. How does a single entity with 37.5% of stake install a supermajority of its own witnesses who do its bidding?

To be clear, this risk always existed on Steem in the form of a dominant share of concentrated stake owned by a corporation. Now we are seeing some of the further consequences to the risk that many people were willing to overlook for four years.

Sure. The thing is that a lot of people have been hoping that the stake distribution would decentralize sufficiently before that risk is realized.
