Don’t forget the fact that he was aggressively homophobic and refused Gene’s wishes to depict the HIV/AIDS crisis in multiple episodes or even have a gay character on the show, including blacklisting a script about the crisis titled Blood and Fire. Not to mention shooting down the Garak/Bashir connection that both actors actively wanted and refusing to allow Malcom in Enterprise to be gay despite his actor also specifically playing him as gay.
There was also the push to have a male actor play the main androgynous alien in The Outcast that Riker falls for. Frakes was all for it. Berman nixed it.
