Not actual physical mobilization but when the amount of mistreatment the team (and founder) behind Roam Research became too much, users started switching en masse and very vocally. It was a lot of drama, I don't think I've ever seen a promising start-up blow the lead in this way. All because the founder thought himself to be the next Steve Jobs and thought that he had a defensible moat (spoiler alert: he didn't) so he could treat his users however he liked and charge them for five year plans without offering a road map.
