Like a class action lawsuit? I think there have to be evidence of damage done in that case.
"Where are the wheels?"
"Well... we delivered most of what was purchased so you don't get to complain."
Ford once paid $300M for a faulty airbags thing, but that was negligence whereas this is fraud. Of course this isn't a lethal risk.
I would think the case would have legs. Haven't a clue how much for.
It sounds like OP is referring to a breach of contract. Even if they can't prove damages, they could still be entitled to some other remedy, like a partial refund. It would depend on the language of the contract, of course.
Go to the supermarket, but a box that says "ten apples". You get home and open it, there's just five apples. You'll want money back. What "damages" do you have to prove?
Unlike that example, it's difficult to know if there were direct damages, but some big companies can come together and try to make a case and sue them and demand huge compensations. Zoom could have spied on your conversations and sold your information to competitors even though they sold the product claiming that they couldn't.
