I read the statement just that at worst, they'd leave the clones alone. As fun as it would be here and other forums to watch the kids bitch about how WiiKey screwed them, the company would still get bad-mouthed to no end. There are bad installers (one posted here recently) that claim to sell legit Wiikey installs but use clone chips.
There are just too many clones out in the world. It would result in too much bad press for them if they bricked those chips.
Wiikey arn't screwing anyone, if anyone is being screwed it Wiikey out of the money for a real chio. You don't even know if its the same build as the wiikey (Soldering, parts used etc...). If the do decide or can brick the fake chips, you've taken the risk of buying a clone.
