Many married women are known under their husbands last names, from Maria Salomea Skłodowska, Betty Marion Ludden to Melanija Knavs. Some celebrities even use stage names, such as Stefani Joanne Angelina Germanotta.

Many of these women are not really known under those names, but somehow, they're still listed on their wiki pages.

Most of the married women on Wikipedia didn't get the choice of keeping their own name, so we cannot really compare it to someone who changed their name.

Same for stage names, people don't use stage name because they want to escape their former name, they use stage names because it's cool.

And when people use a pseudonym and want to keep their real identity secret for personal reasons, their name doesn't appear on Wikipedia, and nobody is ever complaining about that! It's as if people were obsessed by trans people in particular…
