as an extension of this, user stylesheets are interesting conceptually, but practically, web pages became quickly indistinguishable when the same stylesheet was applied to every page. it hindered memory (mental categorization) and recall. users then predictably wanted pages to look different, to have style, and that's likely the principal cause of user stylesheets' decline, not corporate coercion. that's not to argue against user stylesheets per se, but that they'll likely never have wide usage.
