You could call that friend a "perpetual skeptic" or a "vocal non-participant." Another fitting term might be "armchair critic," as they critique others’ ideas without ever committing to a stance themselves. This way, they maintain an air of being "right" by default since they never fully engage in the discussion or take a definitive position.
