JJ Abrams and Justin Lin have every reason to think like lawyers. After all, they make a lot of money from Star Trek, and if there’s a chance something will damage that brand and result in Star Trek making less money, that affects at least part of their livelihood.
So why did Abrams and Lin put pressure on Paramount and CBS to settle and end their lawsuit against Axanar? It’s because these two producers, as fans themselves, know something that all the lawyers involved in this lawsuit (and many of the fans following it) seem to have forgotten: being a fan should be FUN (just change the “a” to a “u”), and when fans have fun, franchises thrive.
