MA is a site governed by a double standard, specifically their alleged "strictly canonical only" policy which they cling to and hide behind as their excuse for why they won't use the term "Kelvin Timeline" (it was never called that onscreen) or why they won't acknowledge Adira on Disco is non-binary (they were never specifically stated to be onscreen). Yet they used the term "Mirror Universe" ever since the site first started, and that would not be spoken onscreen until 2019. To say nothing of all the starships that never had the name of their class stated onscreen, yet MA lists them by that name, or characters who were never named onscreen, but their names come from the credits or script, which MA lists them by. Probably the most egregious example is the Captain of the USS Yorktown from TVH, who MA lists by the name Joel Randolph, a name which was not mentioned in dialogue in that movie or listed in the movie's credits, it comes from the movie's novelization. I'd love to hear how MA tries to rationalize allowing something from a novel under a "strictly canonical only" policy.
MA clearly operates on a "if we like it we'll accept it" policy. Their decision to refuse the term "Kelvin Timeline" undoubtedly earned them points from the anti-Abrams gatekeeping crowd. While the crowd their Adira decision would appeal to most certainly don't deserve to be catered to.
