Perhaps you should not assume shoddy work on the journalist's part. The nits you pick could have been created by editors prior to publication.
However: If I had correctly identified that the piece was shoddy, rather than the journalist, wouldn't materially impact the points in my post. That's a nit.
Including Marvel's existing mis-steps would materially impact the points of an article recounting Marvel's lack of mis-steps. That is not a nit.
