Core put forward BIP103, however the community rejected it by continuing the campaign for BIP101 or BIP109, which left the Core developers no choice but to rally behind the existing 1MB rule, in order to defeat the "attack". The attempts at compromise unfortunately got nowehere. Large block supporters never even put a counteroffer forward.I suppose you did not a reality check, discovering that that was only another stalling technique, and Core has decided to not fork, ever.
