In the 1970s, the BBC had a bit of a problem. You see, people were eating up Doctor Who like it was Doritos (literally - there were a worrying number of reports made about people trying to eat their TV sets while DW was playing). Because of this, the BBC wanted to make as much money from Who as possible, including creating shitty non-canon comics of the series. At first, the comics featured the Doctor and his two "grandchildren" John and Gillian. (Note: the BBC had no obligation to make comics that had anything to do with the actual show. It just needed to say Who on the front. Fortunately, the comics have at least felt in the spirit of the show at times.)
But in the late 70s, everything went to hell. First, the BBC lost the rights to the Jon Pertwee's face as he left the show. Therefor, they couldn't show his face in any Doctor Who comic. Several solutions were put up, including putting Pertwee in blackface as a way to get around it. Fortunately, a black actor happened to overhear, and told them that that would be an ABSOLUTELY FRIGGIN' STUPID IDEA. It seemed that there was no way to continue making comics of the series at all. But then, that same black actor pointed out that finding some other way to change Pertwee's appearance would work. What if the artists intentionally made the facial art crappy? After all, you can't get sued for stealing Jon Pertwee's likeness if the Third Doctor is unrecognizable, can you? 
And thus the Representation Act of 1775 was created. (It was supposed to be "of 1971", but the scribe was either drunk or high, so he screwed it up). It says:
"Any illustrator who is drawing the Doctor must screw up his face to be off-model AT LEAST every other page, and must also screw it up to the point of unrecognizability every 3 pages. Companions are up to the artists' discretion, depending on how much their visual representations cost." 
This one rule has saved the BBC countless amounts of money, and made it so they can produce countless comics without needing to worry whether the actors want their faces plastered on such non-canon material, or whether the face looks accurate. If the face in the comic looks nothing like them, how can the actor complain?
 This black man was celebrated for his genius idea by being put in a comic book as the first black companion, Nick Willard.
 Moffat supposedly mentioned that just saying "he" was sexist, as opposed to "he/she." Some MRAs said that he was just being a "SJW-loving pussy", while some feminist writers said he was being patronizing to women, covering up his sexism with small changes that don't affect the show's misogyny, and being cissexist.
