We also believe that industry-wide consensus around a technically sound and conservative blocksize increase could be achieved following the activation of Segregated Witness.
what is it that gave you that impression?
I assume they simply 'believe' that SegWit is better because it is safer. They do not claim SegWit is the ultimate solution.
I like the idea of Node Community united against Bitcoin Unlimited, but what end users can do exactly other than voice their concern?
Core nodes were always majority, we have 5613 running Core nodes and only 792 BU nodes. Core 82.22% vs. BU 11.6%
I don't see that huge difference changed state of the war between BU and SegWit.
