Publish the fact that it can be done without publishing how to do it (yes, you have to be reputable). I think it's interesting that the lawyer focused on the fact that they depackaged the chip when the (in my mind) bigger vulnerabilities don't require that.
I think it would be interesting to sue a company like CyberLock for false advertising ... "impossible to clone keys" is clearly false.
Indeed, if you do so you must word your blog post very carefully not to make any claims you can't fully back-up with a PoC. Such as being very specific about what versions/configurations are vulnerable.
It'll force you to hire expensive lawyers for all the pre-court maneuvering, which tends to be a good deterrent to any small agency or freelance consultant.
