I agree the infighting is not helpful. I also think that we currently can’t use traditional bargaining and protest tools to effectively punish or otherwise shame those in power into concession. In this case, Musk is an oligarch who owns companies, like Tesla. People are shaming owners of these vehicles and pressuring them to sell because that is a very tangible way to hurt the oligarchs in our country, by hurting their purse. It’s the only thing they care about. It will either help lead towards concession, or ultimately wipe out the power they have. I think this is a form of solidarity, and those who care about that will go out of their way to distance themselves from the oligarchs who oppress us, including when trading or buying within our own class.
