I forgot on what site and how I found it, but I read something from a supposed former intern at Capcom (take this with a grain of salt) explaining that Disney told Capcom to leave X-Men and the F4 off of the roster because Disney doesn't own their movie rights, and to emphasize characters that are currently relevant in the Marvel Cinematic Universe. Capcom was also told to make Marvel characters look better than Capcom characters.
I believe I remember reading about it on Reddit. I also saw a video on YouTube on it, but I couldn't find it in my watch history. Feel free to take everything in this post with all the salt in the world.
