Add to this the fact they try to enforce mandatory arbitration - a thing that shouldn't ever exist to begin with, in any jurisdiction, and is actually unenforceable in many.
Unfortunately, the US doesn't yet consider that a legal right. Sadly, courts take the position that if you don't agree with the terms, don't buy the product. Even in the cases where you couldn't access the terms ahead of the sale.
The legal system in Australia is better because if you win a lawsuit, the losing side usually has to pay your legal fees. As a result, there's far fewer frivolous lawsuits, and companies don't drag out lawsuits hoping the other party runs out of money (which is a common tactic in the USA), since they could be on the hook for all those costs.
I'm just saying that if you can't afford the legal fees, you won't be able to initiate a lawsuit even if there was no such warning on the lid in the first place.
