I wonder what Mike Judge thinks of him? I know he and Parker and Stone seem to get along.
Dunno. Judge doesn't seem to get involved in these types of disputes. He's worked with Groening (which caused Matt to remove his name from that episode), Matt & Trey (as Kenny in the movie), and Seth Green on Robot Chicken (who's a good friend of MacFarlane), so he could go pretty much anywhere on this particular issue.
I don't think he'll make any public statements though.
