Note that mediabiasfactcheck.com is just the personal project of a random right-liberal American healthcare worker; it is not actually some kind of neutral arbiter of bias, and in fact it's heavily biased itself. Ultimately it's just some guys opinion, no better than getting the opinion of some person off twitter.
My point is, you may as well just post a random guy on twitter saying "yeah, I think AP new is pretty legit" and it would be as meaningful as posting mediabiasfactcheck.
