Meh,
I'm ambivalent about this particular drama.  Not using escrow is a "red flag," so I would expect some users to red-tag the account; that doesn't surprise me at all.  It's a decentralized trust system for a reason.  Some people are more concerned about some things than others, and that's why it's designed to work the way it does.

This particular business doesn't scare me the same way other non-escrow sig campaigns have in the past, so I personally don't feel the need tag the account.  But at the same time I don't see any reason to get worked up about others tagging the account.  It's just a tag, which should be taken for what it's worth no matter who left it, green, red, DT, or otherwise.  The other thing to keep in mind is that tags aren't permanent, they can be removed or replaced.  If the campaign doesn't pay you can rest assured I'll be there to red-tag them.  On the other hand, I doubt the current red-tags will remain once they pay the participants.
