Re: Good news
"Agreed, but the bad news is that there's more than enough kit out there to cause havoc and little if any means to get it cleaned up."
Cleaning up what's there may indeed take a long time. But surely there are a few key manufacturers of this kit who could be sued and prevented from continuing the situation. If not a class action suit, then publicly shaming of the these charlatans is at least a possibility. Other consumer devices are required to meet certain basic safety standards. I see no reason why the same principles wouldn't apply here.
