To be fair, the initial point was that Kirk didn't even bother to get Spock back and that Spock had also already plans to leave Starfleet, and was not about that "Permission to come aboard" line. It was criticism against the characterization of the "friendship" between Kirk and Spock. The point was that there was no such thing because nobody of them cared. One of them had to be talked into it by his future self, and the other one went like "yeah, whatever, welcome back" but didn't actually do anything to get him back. But as with almost every criticism against the movie, the "haters" get then pinned into argument corners so that eventually the "lovers" can say "You're so obsessed with pointless minutiae!"
That seems like an oversimplification, but I think it's not too far off. Most people who demand of their fictional universes a lot of consistent, explicated context and background find that the new film lacks that, and it contributes to their dislike, but I think it's an equally valid point of view to not really care about such minutiae.
