Framing it as "obsessive" is an attempt to shift away from subject matter toward an attitude of journalists or consumers, like it's borne of the same attitude as paparazzi. But I think it merits significant coverage not for that reason, but because it so frequently meets criteria for meriting journalistic attention.
I agree that comment sections can be bad, but they aren't always, and to some degree I would rather trust moderation than suppress reporting on a topic of legitimate interest. You're exactly right that a lot of reaction is toxic and politicized, and sometimes the way that manifests is by trying to cook up rationales to suppress stories by flagging them. Out of respect for the concern you've identified, it would be a huge mistake to let politicization win by allowing politically motivated abuse of flagging.
