That agreement seems very general, doesn't indicate that the participants will run specific code. Segwit2x client didn't even exist at that time, first release was yesterday.
Not making it up, talking to real people in the space.
You can also check out the SegWit2x mailing list archive [0] for companies actively testing SegWit2x. From there I've seen BitGo, Blockchain, Bloq, OB1 (Open Bazaar), Purse.. these are significant companies in the Bitcoin economy.
Testing is very different from actually running it in production. Companies test out a lot of different things. I think with consensus code companies will be very careful and if they plan to do something regarding that, they will announce it clearly, not in some half-assed wiki site or medium post.
That's... you're woefully out of touch with how people communicate in this space.
Show me where on these companies' sites it says "We run 0.14.2 of the reference client, with this patch set, and don't plan to ever change"?
Anyway, we'll see what happens in the next two weeks I guess. I'm expecting we lock-in SegWit via the SegWit2x client and then have another debate in a few months about the hard fork. Hoping not too many sw2x supporters get cold feet in the meantime.
People are just making this bullshit up.
