The restrictions are just way too limiting. It's a big universe, and CBS/Paramount should "make" space for proper fan fiction, not beam-it-out in wide-dispersal mode.
I for one, will think twice before spending any money on any new Star Trek ventures going forward. Very, very disappointed.
They are not restrictions They are guidelines.
Also, the only reason to follow them is to eliminate any risk of getting sued. That's it. If you follow the narrow path it lays out, your production will not raise the ire of CBS.
Nothing says you must, but you run the risk of what the Araxar guys are facing. Of course, if you're at this point, it might be wise to not just talk to a lawyer, but talk to CBS for a licensing opportunity.
Because once your "amateur" production starts becoming professional, it might be time to actually license the work. And once licensed, you're free to do whatever the license lets you.
Of course, it costs money - about $50K to enter in licensing talks. But if you want to put in a big flashy production with top names in production companies and such, you might just have the money to actually negotiate a license.
For the rest of us, these guidelines ensure that your kids acting out Star Trek and posting it on YouTube is a safe thing to do.
