There's plenty of room for all fan films, all fan studios.
We have the Potemkin Pictures Open Studio, an open house event at our studios every other year. No admission required. We give tours of the sets, answer questions from our fellow fans, and let them take pictures of themselves on the sets. Everyone has a great time, and we actually find and interview fans and other interested parties (i.e. actors) who are interested in becoming involved with our productions.
The same was true for the annual Farragut Fest / Farragut Open House (held in Farragut Studios, the same studios they transferred to Star Trek Continues, the same studios as Stage 9, in fact). I think they charged some nominal admission fee the last year, but fans were everywhere in their 10,000 sqft facility. Potemkin Pictures had representatives attend the event each year (heck, I did it twice myself). We shared our movies with their audiences and ran a panel for them. It's great fun to meet all sorts of fans and fan film producers.
The Starbase Oklahoma group also had several open house events where they gave tours of their sets, answered questions from fans, solicited help in the form of donations, and, like Potemkin, reached out to fans who were interested in becoming involved with their productions.
While I didn't personally attend Stage 9's event this year, it sounds like it was great fun. They didn't charge admission. Fans got to watch the Dreadnought Dominion group film a production; they got to tour the sets, meet other fans, and basically rejoice in our mutual love for Star Trek.
Axanar opened their sets to the public as a part of their Axacon convention. They were there, answering questions, showing off their sets, and interacting with their fans.
Glen Wolfe and Dan Reynolds WARP Studio D debuted their studios this weekend by filming "Galaxy Hopper" (one of the new releases from Federation Files). I'm sure at some point they'll invite fans to come to their studios, just as the other studios have been doing since before Mr. Cawley purchased a license for his Star Trek Original Series Set Tour.
I can't see the Museum tour being anything like these events, and I'm sorry that Mr. Cawley seems threatened by them.
