Yet you completely ignore that Braga would know if there was a fifth season as he would have to be compensated as co-creator.
I'm not ignoring that fact. At the end of the day, the studio could decide on their own to move forward without him, if he is busy working on other projects. They own the rights to Star Trek
; not Braga. If Braga is entitled to money for being a co-creator of Enterprise
, then they would compensate him, but they wouldn't need his blessing to produce a new series.
