Yeah I gotta agree there is a weird double standard afoot here.
Stephanie Williams who will soon be writing an issue of the Wakanda series is currently writing the Nubia & the Amazons/Queen of the Amazons series which centers on Nubia as the newly crowned monarch of Themyscira. It wasn't even through an election, it was a contest of champions and Hippolyta giving her the crown because she thinks she's the best suited one for the job.
And from what I hear there's no teardown of the system and toxic it is or whatever. Its just Nubia's adventures as the new ruler of the Amazons and dealing with all the interesting ramifications of it and trying to integrate with the wider world as a hole.
Hell they even did a coronation one-shot special celebrating Nubia officially being crowned Queen with the whole thing being treated as a great special beautiful affair. If they really thought negatively of Themyscira then they wouldn't portray Nubia's crowning so positively.
