They destroyed devices that worked perfectly well, but maybe (or maybe not) had a fake FTDI branding on a chip inside the device.
Even the manufacturer may have been a victim of commingled inventory. For this reason I stopped buying anything with FTDI in it, because I didn't want to take the chance it would be bricked because the smalltime seller on Tindie.com bought from a bad supplier.
I would hate to think what you would have Apple do to Hackintosh hardware.
