I was going of the OP article here, the quote is a concern that it makes Trump look bad, not that it is inaccurate reporting.
I do agree with you though, if reporting is wrong then that's the problem. In those cases, and there are plenty, the concern raised should be inaccuracy rather than optics though.
How do you know the coverage is "wrong"? I mean, no news org, not NYT, not Fox, not WaPo, not even NPR can determine if Trump is lying. Sure, they occasionally note that what he says is "baseless", but never lies. So how are you going to determine wrong?
