I am saying they can (if they have the current paradigm of majority hashpower) IGNORE all of the users who don't run the new version. Nodes who aren't corporate Miners and Exchanges don't matter. That's what we learned on Saturday. There is not enough decentralized hash power to even come close to competing with those five companies.
And again, if you don't get on board with the Cartel, you'd have to switch to Ocean (unlikely with the current events) or another protocol that uses DATUM (who?). And I don't think any of these hashing warehouses are even close to ready to do something like that.
