I see what you mean, they certainly don't need the X-Men, but that doesn't mean they don't want them. The MCU could manage without the X-Men but it would be foolish to do so, they are an extremely popular IP who usually make a lot of money and are very popular amongst regular audiences and superhero fans, something the MCU lacks by constantly using unpopular characters and throwaway villains.

They have shown multiple times to have complete interest in getting all of their properties under one roof, even if it means making a deal with Studios and not just being greedy, like they did with Hulk & Spider-Man. The Fantastic Four themselves are tarnished, not the X-Men, they've actually been pretty popular amongst fans (most average joes don't know about this studio drama, they just want good movies). Having that great franchise in addition to their other ones would only benefit the MCU in great ways. Explain to me what reason they would have NOT to do it sometime in the future?

Go on, explain.
