I do not think you used "big conspiracy", but that is how it feels reading your thoughts about HEA. Like some monster decided to fool everyone and started doing things to prepare for a scam that would follow. Kind of like detaching power cords to prepare for selling them aftermarket. That is how your thoughts about HEA development come across, at least some of your thoughts.
Not that I have love for any industry, but it might have all just been a gradual and unplanned development. HEA may be getting smaller these days, I do not know the numbers, but it still seems that every day I read about a product from a company I have never heard of. And they happen to be more and more expensive. Maybe to accommodate for smaller numbers sold? I have no idea, just observations.
