I think you're conflating two points there. Component-based frameworks and utility CSS are completely orthogonal to the use of semantic/accessible HTML. Granted you do see things like divs with click handlers used as buttons by people who don't know what they're doing, but I saw plenty of that in the jQuery days too.
