This is a horribly editorialised title. In my view (as a e-commerce store owner) a false positive rate detecting fraud across their whole network of only 0.1% is very very low. If I'm reading it right, that's 1 in 1k blocked transactions are incorrect, not 1 in 1k all transactions!

> The challenge is compounded by the fact that fraud is rare—on the order of 1 out of every 1,000 payments.

So 0.1% of 0.1% (0.001%) of transactions are incorrectly blocked.
