Tony,
I think you made my point(s). There are two problems with this whole thing: 1 - Buzzkill did not "invent" VV, he took an idea that was already in the public domain and marketed it. That is not invention. Evolv, on the other hand, seem to have been the first people to "invent" the idea of constant power, which is why I believe their patent to that effect would be more defensible (however we will see, I haven't looked at their patent yet, only time will tell on that one)
2 - Your point about costs of enforcing patents and the returns is right on. I would also add the question, in a small niche market like this, what is the point? Buzzkill is obviously not doing it for the money, because, as you said, he's not going to get much money (if anything at all) from these small manufacturers. So why do it? There is only one reason to send threatening letters to small manufacturers, that is to satisfy some sense of entitlement, or just to bully, or something. Either way, it amounts to him being an ...... just because he can.
That's why I object to it. I don't understand why some of the people posting on this thread can't see that. Why would they defend someone who is obviously just being a jerk just because he can? How does that help the industry, not to mention being bad form and violating all the principles of community and helpfulness that the ECF have been built on??
And your point about "Mike, support my vices" : Excuse me, but isn't that what the whole ECF is about in the first place? How about saying "Mike, you built your business with the support of the ECF, but now you want to screw it over?"
I think you've forgotten that this guy wouldn't have a business without the ECF, and now that he's gotten what he wants out of it, he wants to deny that right to everyone else, including future vapers.
How can you think that's cool?
