The ubiquity of responsive design has a direct correlation with the rise of frameworks. Frameworks made responsive design easier to grasp and get started with by producing simple patterns users could follow. Lowering the bar of complexity was necessary to allow engineers and designers to grasp responsive design concepts. If frameworks didn't drive the responsive web, we'd have far, far fewer responsive sites on the web today, and the ones we did have would be far less performant.
Make no mistake, frameworks didn't invent responsive design, but they gave everyone the ability to design responsively with ease. Without frameworks, we wouldn't be where we are today.
