Producers went out of their way to to make Burnham Spock's half-sister. They could have made her raised by a random Vulcan family, it wouldn't have changed her character one bit. But they wanted Spock, Sarek and other TOS characters in the show specifically to tie STD into TOS. We have seen "Klingons", "D7". We have now seen the "Enterprise", and we will see "Pike" (double quotes are quiet intentional). At this point if we do NOT see Spock, then wtf are producers doing setting up the Universe around Spock without actually showing him? They'll be crucified if they don't show Spock at this point. And yes, they'll be crucified if they do, and it's not up-to expectations of the fan base.
So yeah, TPTB run Star Trek in such a way that they cannot please everyone. They put themselves into that corner, there was no reason for them to do it in such a way.
I have an expression that I say in Real Life, that I picked up down the line and made my own: "If you can't please everyone equally, offend everyone equally."
