I doubt he'd have a problem with you. His issue seems pretty clearly to be with people who do not keep their commitments. If you don't start your day before 11 then obviously don't accept meeting invites before that time and you are golden. Oh wait, you work at a company where 9:00 meetings are normative? I guess that job is a commitment too, isn't it?
That does not seem at all clear to me. To me, the clear meaning is that he is addressing everyone who isn't a morning person, and merely using the case of bad-faith promises as an example of their evils. Based on the article, it's hard to imagine he'd feel differently even if the person did not promise to be there at 9 a.m., because — in his words — "earning your life is supposed to be difficult" and anyone who doesn't "put in the work" is "lazy."
