WB doesn’t care about frivolous lawsuits, even from someone as rich as musk. Unless they were sued by him thousands of times at once, their legal costs are already baked into their financials, and if they were sued thousands of times at once, that’d be the easiest dismissal in history, as well as the quickest countersuit for damages.
The rich can bully the poor’s with legal fees, but not each other. That’s why we don’t see uncountable fruitless lawsuits between the powerful - it wouldn’t do anything.
