One key thing I noticed is this is before iPadOS was a thing, so this patch targets iPads too... Which makes me wonder... this is speculation no proof, but I wonder if someone is exploiting Point of Sale devices that are powered by old iPads somehow, which is out of the control of a lot of end-users who are at thee mercy of the POS vendors who are probably charging an insane premium on them.

I worked at a restaurant chain and I remember it being a whole thing to even consider reworking the POS tables + software due to rising costs.
