Imagine the telephone conversation:
ELLISON: Hello?
New Trek Writer: Hi there...I was wondering if I could bother you a moment?
ELLISON: Yeah, make it quick. I really need a good bowel movement about now.
NTW: Uh...I'm writing a new Trek story and I'm sorry but there's a little thing you included in the script you wrote for episode X that makes it really difficult for me to finish
my script in time for the deadline.
ELLISON: Jezuz God how do you yuckamucks find me.
NTW: I mean how do I get around that you wrote ______ in that episode???
ELLISON: First, I did not write that, Roddenberry
inserted it with all the finesse of some impotent john trying to shtup a schoolgirl hooking for lunch money. Second, despite the fact that you're reasonably articulate and apparently capable of dialing a telephone with your little webbed fingers you're clearly some kind of mutant microencephaloid. Star Trek is a fucking TV show, you clown. Fer Chrissakes, it's a kiddie western.
NTW: Uh - what? Look, I -
ELLISON: Listen to me: I Do Not Care. If you were a real writer I'd urge you to free yourself of this baggage, get out of the goddamned guano factory and dream your own dreams...but to put it in language a forelock-tugging yokel like yourself might understand Make Something The Fuck Up.
NTW: Yeah, thanks...
ELLISON: Yeah, you can thank me by drinking a can of Drano and thus sparing humanity another hour of televised pabulum - but if you use anything from my script I'll sue your ass off.
