Unless there's some kind of contractual agreement in regards to it, I don't believe game developers are obligated to stick to any kind of "official" canon.
Disney has absolutely said everything released in any medium will be in official canon, and a "story group" controls it all. How well they stick to that... who knows. Pretty sure there are already contradictions with Snoke and the last movie.
That very well may be, but like I said, unless there's a contractual agreement, non-Disney owned companies aren't obligated to recognize canon. Given that EA seems to be doing exactly that so far, I'm, guessing it might be in their licensing contract.
