Blockstream won't win yet until BU plan to hardfork or SW plan to use UASF, but i agree that non-voting party shouldn't be counted in few condition where update is needed.
But, i'm sure more bitcoiner will support SegWit even if hard fork happen in future.

Also, i wonder if we can accept SW but refuse to support LN

BU has proven to be unreliable, untested software developed by amateurs, who the hell is still delusional enough to support those guys instead of Core?

It's time to wake up and admit defeat, Core wins again. BU is joining the list of hardfork attempts that failed along with XT and Classic soon.

Core calls the shoots and everyone copies then, then they tweak something here and there and manage to fuck up bigly.

We are lucky BU is irrelevant. If this happened and BU was as big as Core is, we would have ended up in a tricky ETH/ETC style situation with the consequent disaster.

Looks like some guys will never learn. They think magic solutions exists to the current issues, BU being nothing but a failed magic trick attempt.

Now if they could behave as adults and start signaling for segwit as advice by every expert on the field including Andreas Antonopoulos, we could move on from this mess and continue improving.
