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...The question right now is not about developers
It is about the economic majority if you failed to notice. This is about neither miners nor developers as such. Basically, it is about those who are using Bitcoin and represented by full nodes. Indeed, you can claim that they don't represent the majority of users and most likely you will be right (to a certain extent), but if we just compare the raw numbers, i.e. the number of miners, developers, and full nodes, the latter will likely have more right to represent Bitcoin users than the former two groups
