But it's not about what Fox wants, it's about what Disney wants since their films are highly praised and Fox is ruining the Marvel franchises under their company. Disney isn't desperate to have the X-men universe apart of the MCU. They have a lot of superhero franchises that can keep the superhero genre busy for a at least a decade, even after phase 4 goes through trilogies of captain marvel, doctor strange, inhumans, black panther, antman and wasp, and new avengers, they could further enrich the mcu properties they do own like blade, ghost rider, black widow and hawkeye films, and legacy characters like sam wilson captain america and so on. Disney does not like to share especially in profits when they could develop the properties they do own and have creative control over and gain all the money from ticket sales and dvd profits.

After Fantastic 4 flopped, Disney would want to distance itself from Fox's brand of marvel. Especially if they want creative control of the Avengers and they do a crossover and the crossover flops, now Marvel is stuck with being associated with a flopped movie. At least Spiderman is manageable. He's one character with villains that rarely go outside of his franchise. The scorpion or Shocker rarely fights Captain America. But if Fox decides to turn Cyclops into a midget, well great, now the mcu is stuck with an mcu cyclops who they don't want to have appear in their movies and is canon and is can't even profit from it.
