I think it’s a bit of an outdated stereotype from back in the day when this kind of frameworks started popping up left and right. It was a major shift from jquery-based sites/apps which scared many people away from diving deeper into front end. Nowadays you can stick to one of the major three and you’ll be fine for the foreseeable future. This new Vue version is the most disruptive change we’ve had since a long time ago in the fe framework space and it’s still ok to get used to.
