The blacklisting code is in every device, even those sold legitimately. That is, the device “phones home.” Some users may not be okay with that.
In my experience, the kind of person who buys an SDR is (a) unlikely to appreciate a $400 device that phones home on boot, and (b) likely to reverse engineer the blacklisting code simply for the fun of it.
