Oof that's rough. I guess a sixth point is "follow through on your commitment" — baiting and switching is a lot worse than having never sent the email in the first place.
Agreed. It gives me a bad impression, which means I'm less likely to want to actually meet up with them, and that puts me in the awkward position of having agreed to meet for coffee and then now declining further invitations. I don't want to burn any bridges, but at the same time, I'm not interested in working with someone who'll do the bait-and-switch. It puts me in a very difficult situation.
