Yeah, and this sucks to say, but this is a case of different circles. When you’re that rich, you tell people hey, why is this guy…, and then your legal team sends a cease and desist letter.
It isn’t suing him, it’s telling(telling) him to stop it please, legally.
She’s so rich that it’s very scary, but it’s basically like a neighbor knocking on your door, with the very important caveat that if her steel toed stuffed animal boot decides to kick your door in, you have no legal recourse, since you can’t mount a proportionally paid legal defense.
In more free countries that are more supportive of every citizen, this wouldn’t be a big deal. In the United States, since money has been legally transmogrified to free speech, it’s more of an issue.
