I dunno, on one hand, I agree with ya, Turing was a major (if tragic) figure in gay history. On another, it bugs me quite a bit when Hollywood all but screams "THIS PERSON IS GAY" at the viewer, and making it their key defining feature. I prefer it when "gay" is just another part of a larger character, not their sole defining feature, but here...not having Turing's homosexuality be a large part of his character might not be appropriate.
