It's possible that Jeph is entirely self-aware of how far he's taken Moray and is in on the joke on this one. I try to make it my default assumption that webcomic creators don't bend their stories on the whims of forum whiners.
But it's hard to read yesterday's t-shirt strip as anything other than a direct "Take That!" against audience complaints that Moray is just a barely-justified walking fetish.
