Perhaps the project “Star Trek Axanar” rings some bells around here, it was a damn disgrace what they did to those people who merely wanted to bring a new chapter to Trek.
Axanar was shut down for using the Star Trek brand to sell extra material, branded items and so on, which they had no right to do. Star Trek Continues was allowed to continue with CBS’ blessing because they never sold an IP they didn’t own.
They also never even had a working script, lied to donators about how much they actually had filmed (the material for the documentary teaser), and funnelled the donated funds into the main guy’s personal studio.
Your concern is valid but Axanar is a terrible example to use as they effectively shut themselves down due to all the fraud.
