In case you were unaware, the reasoning is due to movie rights... Marvel sold off the movie rights to many of their characters years ago and so other studios made movies featuring the X-men, Fantastic Four, Daredevil, Elektra, Blade and so on, but these movies were never connected, just stand along stories (apart from DD and Elektra).

However when Marvel Studios was founded and produced Iron Man, they started buying back the rights to their other characters so that they could create this shared universe which this wiki is dedicated to.

The problem is several studios refused to sell the rights of the characters back to Marvel Studios, which is why it took so long for Spider-Man to join the movies (the Tobey Maguire and Andrew Garfield movies are not part of the MCU storyline), and why the X-Men are yet to show up alongside the Avengers.

Sony Pictures have a somewhat strange deal where they more or less rent the rights to Spider-Man to appear in Marvel Studios' movies, however they hold the rights to many of the other characters, which is why we recently had a Venom movie which is not connected to the MCU at all.

Does this make sense?
