Yes she was in charge of the team responsible of producing the image from the data, it doesn't mean in anyway that she's "behind the first image of the black hole". Everybody involved is behind the image.
This is not about celebrating those people, it's giving the main chunk of the credit to this person alone. I have no idea why is it such a hard thing to understand or why is this even an issue. Claiming that this person is the only "crucial" person involved is a straightforward lie. If that's how the media has been doing it for 30 years, then the media needs to change and fix their lies.
