I have to log in to post a reply to this, so I’ll write a short reply here instead:
Kevin, you are calling group 3 a “vocal minority”. But you present no hard data about how many people are actually in each group. So there is no evidence on which to say that this group is a minority, or even that the responses break down into these four groups at all. You hope that group 2 is large, but where’s the evidence that people really did check their firewalls and re-enable SELinux as a result of this pointless key change?
