Axanar looked awesome
I saw the "Prelude to Axanar" video on youtube last year and thought it was awesome, and I was so looking forward to the final version.
Several other fan produced not-for-profit productions have been made and paramount seems to be OK with them so long as nobody profits from it. I dont really know why Axanar is different. However having seen the the other productions I suspect Axanar is actually being sued for being too good.
IDK why Paramount didnt just buy them out .
