So is it an attempt to stop the User activated fork getting traction ?
yes, because the period from august 2017 to november 2017 is the enforced period for Segwit ... not the LOCK period.
https://github.com/bitcoin/bips/blob/master/bip-0148.mediawikiso Segwit2Mb is a trap.
they want introduce the 2Mb before SegWit LOCK.
So the folks who want 2Mb don't trust the SegWit people not to break away after SegWit is locked and block a later block size increase?
Sounds understandable given the emotionalism on this issue. It would be very disruptive to activate SegWit and then deactivate it before LOCK. Seems unlikely the miners would do this. It seems far more likely that the SegWit folks would increase their opposition to a block size increase to 2 Mb once they already have what they want.
I am not understanding why this is not a reasonable roadmap forward.
