At their scale, it is entirely possible that this wasn’t malice, just bad algorithms/poor testing. All they had to do was say sorry and fix the recommendations. Instead, they’re lawyering up for a fight.

Just how much profit are they making from these kits? Must be negligible to them? I don’t understand why they think it is worth fighting this? Or is it their policy to always fight, never back down, never say sorry etc? I honestly don’t understand. Even ignoring ethics and looking at it from only economics, it doesn’t make sense to me. What am I missing?
