You're surprised that companies that can be sued are standing by their commitments that keep them from being sued? I'm more surprised bitcoiners don't have the faintest understanding of keeping business commitments. Of COURSE they are all going to 2X. They agreed and signed that they would. Any loss of value to others for going back on that commitment would lose them a court case.
Who's going to be suing who? What court would take the slightest interest in this? It's a loose conglomerate of miners who are free to wander off whenever they like. On the very day it was signed there were people who 'signed' it who didn't know the actual details.
If it does happen the only lawsuits flying will be against any exchange that lists 2X as it won't have repay protection, so no exchange will list it.
I'll be amazed if this fork happens. People don't bet tens of billions of value on something put together by a handful of nobodies behind closed doors forcing a fundamental change in a few weeks that no one outside the room it was created in agrees with.
Segwit was established and thoroughly tested and it was a soft fork. 2X is none of these things.
The players will gradually bail on it as November approaches.
