Not sure if emulating USB Blaster interface violates FTDI licenses. I rather assume that USB Blaster driver is licensed by Intel. But as it's a renamed 1:1 copy of FTDI driver, the built-in anti counterfeit features are in effect.

Well you can emulate FTDI only if you do not use FTDI drivers. But that the all point of emulation. I am pretty sure that using FTDI drivers with non-FTDI IC is violation of the drivers use license by FTDI, see screenshot above.
