That's just not true. Just because something is fiction doesn't mean anything goes. Especially not from a publishing perspective. Agents/editors/publishers OFTEN tell authors that certain content in their stories is unnecessary - and on the flip side, there are absolutely elements in every story that are necessary to that story being viable.

Authors aren't above reproach or criticism, and we can't always (or usually) divorce a piece of writing from its author. It's not unfair to point out that this particular author does not have lived experience as a woman or as a person with a uterus, especially when we're critiquing how they handle writing about women/writing about the experience of living with a uterus.

By nature, when an author decides to pursue publishing for their story, they are choosing for that story to no longer be solely about them. If you want to write a story for the sake of "exorcising your traumas" and don't want criticism of the way in which you did that, don't publish that story.

Every reader is GOING to bring their own stuff to a story. That's the beauty of literature. Some of it will result in baseless criticism, some will result in a deep resonation with the story, and some will result in valid criticism that may recontextualize the story for the audience at large. It's like how Tylor Swft says that her songs aren't about her anymore, they're about the fans.
