As a soon-to-be FO I can agree with that, not cool at all. On the other hand though, could you imagine being stuck in a cabin with no air for endless hours and people throwing up? I understand the flight crew can't do much about it, but I think that was a fairly extreme situation. I sure don't have a solution, but something should have been done IMO. As a flight crew member however I would have probably taken similar action as you proposed in addition to trying to figure something out with the company.
