Dan Lyons didn't mention expensing lunches in that article. You are speculating why your book was mentioned. The issue you seem to have is the bit about your "tour of duty" concept, which it looks like was indeed mischaracterised (I have to read your book to know for sure). But apart from that I'm not sure what can really be stated as anything else than fair criticism in that article - and by which I mean he disagrees with your ideas and critiques them.
HubSpot fired two senior managers because they tried (foolishly) to use deception to obtain copies of Dan Lyons' book before it came out. You seem to be implying that our book promotes such unethical behavior. Again, I'm unconvinced that describing a program for allowing employees to expense networking lunches constitutes encouraging an abusive culture.
