Will 'Deadpool' Be On Spiderman?

Disney purchasing 20th Century Fox has caused many fans to wonder what will happen to their beloved 'Deadpool' franchise.
Rumors started that 'Deadpool' might be introduced into third Marvel Cinematic Universe Spider-Man movie.
The creator of Rob Liefeld has denied these claims on Twitter.
His point made a lot of sense. Why would Disney give Sony Pictures the right to 'Dead Pool.'
