Most people got tired of Wolverine. He isn't even the highest seller. Spidey is a better example there. But they also have done events ad nauseum and that fatigue is showing up in sales. They are still doing floppies, despite those not doing as well as manga style. There will be overlap in what fans want and what they do. But not always. Which could be why comics still struggle in sales. But also because they plan things out months to years ahead and they aren't gonna change no matter what fans want. The only time that has happened is if something becomes really controversial.
