If we are using your definition of "canon", then Rogue One AND the noveld comic whenre it was revealed that the Death Star was sabotaged because Chewbacca took a nasty shit on the restroom are both canon at the same time.
There's a lot of stuff from IDW that is contradicted by the show...King Sombra's redemption, Chrysalis' origin, Storm King's entire personality, the whole Anon-a-Miss incident... and keep in my that the MLP comic was part of the Deviations event, so by your definition of "canon", MLP exists in the same canon as Transformers, Ghostbusters, Teenage Mutant Ninja Turtles, Orphan Black, X Files, Star Trek, G.I. Joe, Mars Attacks, Popeye, Judge Dredd, and anything else that is part of the "IDW Universe".
Bottom line: there's a difference between "canon" as you define it and "canon" as everyone else defines it.
