In a sense one may get the impression that Steemit inc's development team would be the government supplying the subsidized power to the miners/witness on on STEEM in the form of their weighty votes?

Not complaining in the slightest. It's good to know the core developers of STEEM took measure to protect their invention for the greater good.

I guess my actual question.. While I see how you've proven how BTC could infact be easily manipulated by govt's supplying the electricity.. How does our DPOS system work to prevent this?
