This isn't the first time there's been a shake-up with the New Voyages/Phase II people that gets made public but without any explanation. Back when Jack Marshall left, a big pomp and circumstance was made about how he was leaving but no explanation offered publicly. When posters inquired why, Jack got super defensive about it.
On a somewhat related note, I wish fans and friends would stop going nuts every time an obscure Facebook status appears. Clearly Cawley is having some issues with some people, and if it's because of the a-hole Trekkies out there, that's unfortunate. He's been doing this show for all these years as a labor of love and he's been kind enough to share it with us. That people are unable to offer their commentary in a constructive way is saddening and it's why I find myself hating Star Trek. Not because of the productions but because of the many, many assholes that call themselves 'fans.' Besides, even if Cawley were shutting down production, I have no doubt that there would be a PR announcement from him or at the very least a (lengthy, informed) post from GSchnitzer about same.
However, I will also agree with Maestro's point and expand it further: Cawley is re-interpreting a famous, beloved franchise. This isn't Exeter or Farragut or Hidden Frontier where most of the characters are all original creations, Cawley specifically resurrected the original big boys from the show. And more power to him for doing it successfully... but people disagreeing with your take on things, people not liking what you do, from Elvis hair to goatees to modern visual effects ... it's part and parcel for the entire endeavor.
But this same issue is also why I'm a little irritated that Cawley is trying to do same with the Wild Wild West and to a certain, lesser extent, Buck Rogers. Certainly I'm not against the guy doing what he wants to do, and I love that there will be new product out there ... but if the negative fan reaction is to the point that it's getting him down (and I admit I am totally filling in the gap there) then I kind of have to wonder why he'd be setting himself up for even more of it? I mean, clearly the resources are there to do pretty much anything the P2 guys want to do ... and licenses and rights aside, while Buck Rogers is at least something they can make some money off, it's not exactly venturing in to original territory for them.
