TDLR: It is a fake contract, and sheeple being tricked without recourse in Contractual Law.
In order for a contract to be valid where the supplier takes on liability, there has to be an "exchange" where the someone pays for the good offered by the supplier.
If I give you a lollipop laced with poison, you can still sue me even though it was free.
If I did it with criminal intent, you can charge me with a crime.
Except if it kills you, who sues? This is what they counting on. One legal way around this is to make a person’s estate one of the Plaintiffs (if you or family have been poisoned and might die before conclusion of litigation).
