Why should a customer be punished for buying products that are not banned by the government and for tripping up on an invisible tripwire within said product? If there were a definition for "set up to fail" it would be that customer... Or are we to assume google is a potentially hostile force, whenever it feels like being one. We used to ban the sales of products that harmed customers.
