It's not like I had physical injury because of his "apology" either, but this is absolutely morally wrong behaviour even if we specifically weren't affected by it, intent matters more than anything, and instead of actually taking to heart that cold mailing (which I don't think is even nearly as bad to start off with) is unfavourable he decided to strap on several layers of even more highly questionable behaviour. I know technical people don't do sales really well, but that isn't really a good excuse for doing this instead, and I don't believe we should allow this to happen without negative criticism.
It's not like this is an effective sales tactic either because intent matters and this is a clear demonstration of lack of ethical and moral values that could directly correlate to how customers are going to be treated.
