It seems as if this is a really expensive way for CBS/Paramount to solve the problem.

Instead: Why don't they have the Axanar folks organize in such a way that they qualify for SAG indie film treatment, or fan movie status under some kind of SAG fan movie contract, then, have CBS/Paramount make the intellectual property, plus $1 million, available to the Axanar folks in exchange for ownership of the show, distribution rights, and the right to keep most or all of the project-related revenue?

Maybe, as part of the deal, CBS/Paramount could require the Axanar folks to put in some kind of alternative universe mumbo jumbo that would keep its timeline from interacting with the regular canon Star Trek timeline.

The Axanar folks would get the money they need to do the film.

CBS/Paramount would get a cheap Star Trek film.

CBS/Paramount and SAG could probably figure out some deal that would let fans do micro-budget fan movies inside a union-friendly framework. The legal work for creating that deal might be cheaper than the legal work for suing the Axanar folks.

If there are specific rights problems for CBS/Paramount (example: questions about who controls the music), then CBS/Paramount could use the fan movie framework to make it clear what fans can and can't use and do.

By creating a standardized fan movie framework, CBS/Paramount could get a cheap stream of content along with control over the content. (Example: it could retain the right to block racist fan movies, or porn fan movies.)

I think that, also, if CBS/Paramount created that kind of legal framework for fan movies, it would look a lot more sympathetic when it went out to block Trek porn movies or whatever.
