Wow, you reeeeally want to die on this hill, huh?
You're even starting to contradict yourself in your comments. How many times have you now said "The show has tons of contradictions in its own canon", and yet you posted this image to say "This is the REAL canon, according to me, contradictions don't matter.
A voice actor does not have control over their character's sexuality. They don't have control over much of anything about their character. If you were somehow hired to provide a new voice for Goku, and then went on Twitter to say Goku is bisexual, that doesn't make Goku bisexual. Voice actors can have headcanons just like the rest of us, and for the most part they're free to express them as long as it doesn't get them into any legal trouble with their employers. It doesn't make it canon though.
Likewise, Faust's tweet in 2016 holds the same amount of water, since she had left the show in the hands of others by this point. In 2016 Faust didn't have a say in what direction the show was going. If she suddenly decided one day that Discord was polyamorous, you think she could just call up Hasbro on the fly and say 'make it happen'? Faust has already gone on record stating that one of the reasons she left the show in the first place was a "lack of creative control". After she's already left the show after season 2, she's gonna have way way less control. But, again, she is free to have her own headcanon interpretations, and it's true that they may hold more water because she is the character's original creators, but that still doesn't make it CANON.
As for the comics, then we get into a bit of trickery with language, specifically how you define canon. Is Ocellus into girls? Based on a panel in the comics it's a pretty good indicator that she is...according to __comics canon__. As repeatedly statesd, the comics have no influence on the show itself. So if the show had continued past its end, it's perfectly within reason that the showrunners would decide to make Ocellus straight, despite the comics canon. How do YOU define canon in this picture? Talking about the show itself, or just "they're gay in SOME kind of canon, one or the other".
