Segwit2x was only "anti-developer" if you only consider the "bitcoin core" developers. There were many developers quite interested in larger block size for many years, since before the February 2016 "Bitcoin Roundtable" in Hong Kong. Segwit2x had over 90% of the hashpower of the bitcoin world voting for it, at one point a couple months before it was to activate. Hashpower is heavily tilted towards large mining pools, many of them in China, but it is still the best measure of consensus and support the network has. That's a major tenet of Bitcoin in the first place. (Though I wouldn't say "only miners matter" nor "only users matter", the network really needs both to work.)
I think that the survival and modest success of Bitcoin Cash eroded the initial overwhelming support for Segwit2X. Though if you mostly read /r/bitcoin I'd say you have a very warped view of what happened ;)
