Yep, it's the price difference that bothers me. $450 versus $15.I think it's possible to find the USB cable and the software to read/write inside the ECU.
I've seen them in my dealer workshop and they seem to be common.
There are no licence protection on the software (key or dongle) and no partnumber on the cable.
Newer triumphs like the Tiger 800 record if the ECU has been accessed using a non Triumph tool to show that you've invalidated your warranty.
