With SV, the developers are the miners. They run the biggest mining pools. If they say SV wants to give control to miners they are saying SV wants to give control to CSW/nChain/Calvin.
Hopefully after they "gain control" they'll encourage healthy competition between pools. With a real bull market and increasing institutional adoption mining will get very competitive
Bingo! "Gain control" is a phrase used to frighten and(ironically) control you. The only way C&C win after gaining majority hashrate is by making Bitcoin amazingly good money.
