Crikey. Yeah, this has Isaac Perlmutter (the guy intimately involved in Marvel's bankruptcy back in the 90s) written all over it.
The sense of some of these items seems to depend on how you think causality works. Does a Fantastic Four comic actually increase Fantastic Four movie sales? Or is it the other way around? Do X-Men toys encourage Fox to make another X-Movie, or do they simply profit Marvel who has the license for them?
Given the relative size of the comic book market to the movie market, it doesn't make much sense to me.
There are some interesting, even legit items here, though (e.g., not introducing new characters as mutants / X-Men because then the movie rights automatically go to Fox). On the other hand, making the Fantastic Four un-persons in the comic book Marvel Universe is … um … kind of goofy (esp. since that seems to also sideline characters like Galactus and Doctor Doom and the Skrulls).
Bottom line, though, it all seems to e something coming from above and outside, and I don't necessarily think it's a Disney thing.

None of this surprises me. Now that Marvel has a successful film studio going I can see them doing everything in their power to get the rights back for the characters they sold off in the 90's. It also doesn't help that they're owned by Disney who holds onto its IP rights so jealously that they've been known to sue daycare centers that painted Disney characters on the walls without permission.
