I'm not sure why people are so downhearted by this kind of thing. It's well known that anything controversial on Wikipedia is going to have a lot of edit warring and people trying to control a narrative. What Wikipedia is best at is non-controversial topics. And that has always been the case. Even for controversial topics it's honestly surprising how more or less correct the articles tend to be.

Wikipedia is not where you read up on the war crimes that may have or may not have been committed by some country or the views of a politician on immigration. Wikipedia is where you read up on Mars's atmosphere or how solar wind works.
