Cores roadmap with SegWit is the best way forward. It is only being blocked due to some bad actors wanting to keep their secret advantage intact. Jihan Wu himself has acknowledged this. He likes SegWit but does not want it for reasons he cannot justify (Secret advantage).
Says whom... the developers? They are not gods. Developers can make mistakes too. Don't assume anyone who opposed Segwit is a bad actor. Not everyone is a sheep that simply follows thy leader to doom. Some are actually capable of using their own intelligence to decide for themselves whether segwit is good for bitcoin or not.
