That’s your opinion. I disagree. With the glasses they probably needed lots of filtering by hand. Costed them a lot of money. They were afraid of costly lawsuits. But they don’t have the capacity to do that with every product they sell.
They’ll invest the resources to ensure that doesn’t happen.
Amazon didn’t get big by being stupid.
Your point stands.
The bogus ones could then have been isolated and recalled, but this is not what happened.
1) Goggles used the existing supply chain. Which, as noted, was designed around the idea that customers would rather have cheaper things from any vendor that things from a specific vendor. Presumably the greenfield / acquired med supply chain is engineered around different desires and regulations.
2) By the time the goggle issue came up, inventory was already in the system. With some presumably co-mingled. I'm just saying I wouldn't want to be the DB analyst who got tasked with untangling that.
