Kind of similar to how some companies with a lot of money bully people into submission by suing them with the intent of forcing them to run out of money, even if when the company wouldn't actually win the case.
I so wish we'd get Euro-style loser pays (it's really Judge assigns fees, and one party doesn't pay everything, nor do they let expensive lawyer fees be billed if they're unwarranted, etc).
Then companies could be more "Bring it on" when things are totally out there.
I believe it is fairly common in the US for victors to be awarded money to cover their legal fees. The problem is that none of these companies being sued are confidant they would win, and they don't have the money to cover losing.
I think the other part of that problem is that, even if they could be guaranteed to win and have their costs paid, the whole process could take a very long time, and they have to be able to pay all those costs in the meantime.
