Why are you so confidently advocating for a "safe until proven unsafe" mentality here? The health impacts from this contamination are completely unknown, and could impact a lot of people, and their children, etc.
EDIT: down vote all you want, armchair reasoning does not prove that this contamination is safe - cite some relevant scientific literature to support your claims
In doing my part to stick to the topic at hand, I tried to find some research which supports these claims about stainless steel. It seems like Nickel is typically a component of stainless steel and is generally not something you want to have in your body[1].
I'm also not sure how the additional iron, presumably being processed by the liver, might affect someone who has cirrhosis.
I assume "nothing to worry about at scale" really means "not likely to immediately kill a bunch of people".

Here are a couple more good papers I skimmed through today while looking into this topic. I agree on the "not likely to immediately kill a bunch of people" point. From what I can tell, there are very few longitudinal studies evaluating the health outcomes from metallic corrosion and wear from implants.
Citing [1], stainless steel corrosion is associated with "distinct inflammation and tissue reactions in the surrounding soft tissue with high amounts of particles".

The batch is being recalled. They think it's nothing to panic people who have received it based on us having decades of blood-contact data for stainless alloys.
If you're going to attack the messenger, at least read the message.
