I'd say that it has an impact on the Marvel Universe as a whole because the current comics have become by-products of the movies (contrary to the vintage comics which are still a source of inspiration for the movies ... Yes, it is an Ouroboros).

But, yes, I don't think that the current writers & editors have a lot of freedom with the characters currently because one of senior-level executives might be afraid that it kills the goose that lays the golden egg.
