It is well known that Roddenberry started the trend of wanting to avoid too much reference to TOS. He wanted TNG to stand alone. Hence his initial resistance to having a regular Klingon character and why they attempted to develop the Ferengi as the new threat. We really didn't see any traditional TOS baddies until finally the Romulans popped up at the end of season 1. But he also wasn't an absolutist about it. McCoy appeared in the pilot. They did a direct sequel to a TOS episode. Etc.
Berman took that attitude to an extreme level. The writers have recalled how when Sarek was doing his mind meld with Picard, Berman didn't even want him to mention Spock. They had to fight to get to say the name just one time.
But as things progressed, TNG (and then the later series) turned a corner and things softened. Obviously, every single major TOS character, with the exceptions of Uhura and Chapel, ended up appearing somewhere along the way. By the time of Enterprise, all bets were off and there were numerous tie-ins to TOS.
Should Berman have been more accepting of TOS references and tie-ins? Probably. But it was probably also good for TNG to stand on its own.
None of which changes the fact that this argument started because a poster claimed that Andorians never appeared in TNG, which is wrong, because they did. ?
