Of course he did.  He thinks that if there are 5 mining pools, with each of them 20% of the hash rate, and 4 of them switch off, the 5th one will continue make blocks every 10 minutes.

This is the argument he used for a mining pool to leave the agreement he has  with his peers to remain on their mutual protocol, and to switch to the protocol the full nodes want to impose on the miners, because "then he is alone and will make blocks every 10 minutes, pleasing the full nodes and reaping in all the rewards".

My point was that
1) this was not the Gedanken experiment that needed to prove that full nodes can force their protocol onto miners
2) the betraying node is not winning anything, because he's not making blocks at any faster pace than if he remained faithful to the other miners and their agreed-upon protocol.
