Yes, I've seen a fair few shagged Alarm ECUs across a range of Vauxhalls now where a certain dodgy code reader had previously been used to program a new fob. I've seen a fair few shagged NCDC units as well, when people try to play with them.
Whether or not it inflicts the non-Chinese illegal copies, I don't know, as I don't know anyone who has the official one. Certainly if you had the official one, you'd likely have some comeback.
Its a reasonable tool for code reading and live data - its downsides in this respect is it won't touch many ECUs, and the live data updates are too slow (and the interface is a bit crap).
On the upside, I make decent money off those who have been stupid enough to program with it, esp those who shag their immobilisers, and want me to travel to them.
The reason why we do not allow discussion of the cloned devices is because the manufacturer of the genuine device has been quite successful in shutting down sites promoting the use of the cloned ones, and at the time, I was already dealing with threats from another set of solicitors over some of my web content, and couldn't afford more grief.
