They aren't even trying to hide this tbh, they've said in multiple interviews that she's a "sidekick" and doesn't get as much priority as origins, also that combined with their patchnotes about updates to her non-existent kisses makes me really think more and more they just aren't aware of her current state in the live version
Their support team have stated they're "aware of the issues with Minthara" so I'm more inclined to believe they're just putting her on the backburner - which would be totally fine if the basic problems were fixed and she functioned like every other companion, but we know that hasn't been the case
Sad part is, I wouldn't even be as mad or disappointed if it was just Astarion or Karlach getting the attention. Halsin is not an origin companion and is supposedly Minthara's counterpart, seeing as they're planning the ultimatum for us to choose between them, but even he has a fancy kissing animation now while Minthara's is still bugged. He only has one major bug that I know of: his point-and-click lines aren't working.
If it's not her code being "too complex" then yeah, this is all just bias and pandering to the majority. If Minthara's recruitment were more appealing or straightforward, no content loss, no KO exploit needed, her fandom would be bigger and Larian would probably prioritize her more.
