Would it have been annoying to have F2pool later say they only showed up as individuals and the pool would continue to mine on Classic? See a similarity?

The issue is that there is a very good chance that Blockstream as a whole refuses to go along with the HF, which is fine, but what exactly is the point in having Adam as President of Blockstream then? He might as well just be "guy that doesn't code at Blockstream" then.
