I wasn’t aware you can sue your customers when they decide to not give you their business anymore.
Imagine Walmart suing people, because they shop somewhere else now. Or your plumber because you called someone else to unclog your toilet.
It doesn’t sound like Musk is suing them because they broke any contracts, just that several big advertiser spoke to each other and decided not to renew contracts because of rising antisemitism, hate speach and fake news.
I mean, I tell people for 30 years not to buy Nestlé products because of their disregard for human rights. Can Nestlé now sue me too?
