I do not know why everyone is saying is dead, they said the cancelled the hardfork, does that mean is dead.  According to what I had been reading and what they have said is they cancelled due to a consensus in the bitcoin community.  Also we do not know if this was a manipulation event as well, there are alot of factors and I think people looking at this one sided is quite funny.  At least now we know that bitcoin will be able to get upgraded to the lighting network much sooner thanks to segwit.

"While this fork won’t happen, SegWit is here to stay. So let’s see if companies and developers are going to take advantage of SegWit in the coming months."
