It was an overreaction which, however, was only enabled by absolutely lazy journalism. They basically took Bouman's Facebook post with a photo of her smiling next to the black hole claiming that she produced the picture, blowing her contributions way out of proportion. Some reports corrected this later that day, but by then, the shitstorm and investigation had already started. Perhaps understandably--she did not produce the picture. One could argue that Bouman's reaction was also way too delayed and she did not enough to clarify the situation, but this is perhaps understandable assuming she did not follow social media very closely.
The entire fiasco was mainly caused by the obsession of the media to put women at the forefront.
