No.
And, as for the "fans want nothing to ever change" canard, that's an oversimplified cliche. What fans are really railing against is
inconsistency. Changes that occur need to be consistent with what's come before. They need to feel like an organic evolution and extension of the past. For example, when previously heroic, upstanding protagonists walk out on their families or cheat on their wives, that's inconsistent and offensive. On a more meta-level, when a long-standing hero's decades-long marriage is retconned away via a blatant, out of character deus ex machina in order to satisfy the editor-in-chief's personal preferences, that's inconsistent and offensive.
Change is fine as long as it
makes sense. Ensuring that sort of consistency is the job of the editors. That's where the creative buck stops, and that's ultimately who's to blame for inconsistent character portrayals, flagrant disregard for continuity, and poor stories.
As for the state of Marvel more broadly, many of its problems are endemic to the comics industry as a whole. There's never been much of a culture or ethic of professionalism. The business side has historically been petty and dirty as all get out. Most importantly, though, publishers remain wedded to an obsolete business model.
Read accounts by people who've worked in the industry for a long time. As a fan, it does ruin a lot of the magic for you, but it educates you as to the reality that writers, artists, and editors have to deal with. I recommend starting with Jim Shooter's blog at

Marvel Comics: The Untold Story.
