The problem is that I'm not sure there can be "mutually assured destruction" when one group has much more power to dictate the narrative. The media can't completely control the story, but they certainly have lots of influence. Just over the last couple years there have been:
* NYT editor apologizes for racist tweets about Jews and Indians [0]
* NYT editor demoted for past racist tweets [1]
* NYT editor apologizes for racist tweets about white people [2]
* NYT stands by editor who made racist tweets about white people [3]
However, the only punishment received by any of these people was a demotion in the case of [1]. Meanwhile, the paper has the power to put out articles that shape the narrative, deflect attention away from the tweets in question, and reframe the story as an attack on journalism by nefarious actors [4]. Meanwhile, if a non-member of the media, particularly in the case of an average person like Carson King, has their past tweets dug up and reported on, they don't have anything close to the same voice to defend themselves, and are more liable to be treated as a pariah by the public or fired by their workplace.
