Actually HAI has come a long way towards helping with the DIY crowd. They have multiple memberships with our forum and participate in discussions and trouble shooting problem with their products!
Years ago, this was not the case. I think its great that they have acknowledged the DIY types and their participation on this forum is evidence of that.
CocoonTech stops at HAI's booth at least once a year during CES or ISC West and they are more than happy to provide info regarding their latest products and other happenings within their company to us.
We all have to remember that the DIY volume is almost negligible in sales when compared to dealers. What they do gain and realize is the DIY offers insight into various uses and possible problems and testing of their products, which will make them better in the end.
The main emphasis of a company such as HAI though, has to go with their bread and butter first (dealer sales), or they just flat out will no longer be in business.
