Not really, he had a deal and retained a lot of creative controll more than most people would have got, the series had 3 failed scripts, 2 failed pailots and 1 failed episode but was allowed to carry on, he got more and more control for each failure and then kept it, Trek was nearly dead before the first film and it only got a revival as a film because Paramount wanted a franchise to compete with Starwars and dug into there own IP back catlologe and the obsessive fanbase was the selling point.
79/80 Galactica was a second choice by general sci-fi fans even after watching both series apparently, Trek only won by a small margin and Rottencunt pitching all manner of shows and spin off, this included Trek phase 2 and it was partly because of Roddenberry and the other writers liking ideas for scripts they had to move it on in time or they would have to pay royalties.
This crap has always existed over trek, and they will spend more effort to invent a fiction than pay royalties
