Adding to canon is not the same thing as destroying canon
At San Diego Comic Con, we learned that Sonequa Martin-Green’s character, Michael Burnham, is Sarek’s adoptive daughter. The second I heard the news, all I could think was, “Let the hate begin.” And boy, did it ever.
I understand the disappointment, particularly with fan fic writers who invested a lot of time and effort into crafting stories that fit neatly into canon. Amazing how one sound bite can bulldoze right through decades of widely accepted fanon, huh?
