If you think that nothing of what I'm saying makes sense just because I believe that miners are rogue (they are selfish brutes, anyway), then you will have hard time defending your stance, i.e. proving your point for real (and no references to Nash, Nash equilibrium, and other buzz words will help you in that). Further, I said nothing (this is where it actually comes down to nothing) about Bitcoin centralization around developers. BIP148 proposal itself is about giving power (back) to the economic majority. I can't possibly see what that has to do with developers as such (unless they are the economic majority, of course)
Who lied one year ago with things like "We promise segwit with 2mb block size"... An segwit came with no blocksize increase...
Not the miners, as far as I can remember...
