The key detail he's missing is that cryptocurrency node operators run software on their own computers on a purely voluntary basis: they have no contractual obligation to run any particular version that operates in any particular way.
This means any node operator can fork the software to operate as they please. There's no reasonable argument for harm, because the party claiming harm can simply run his own desired version of the software on his own computer. This just means there are now two "forks" of the software on the internet.
The "winner/loser" in the above case is just who gets the most users and which token gains the most economic value.
Note this happens all the time in cryptocurrency: that's why there's Bitcoin, Bitcoin Cash, Bitcoin SV, etc...
and you learn new stuff every day :)
