I get what @C4junkie is attempting to point out, but it's foolish to think that way. If Amazon, Apple, or Google bought Control4, then I could see DIY being a role and that would have been a sell out to everyone aside from homeowners. Snap AV is the opposite and the few announcements have reinforced the dealer model is staying.
Why would dealers want to change a model that ensures them exclusivity on configuring the product? That's the essence of the CI market.
I get that homeowners would like to be able to do it, but it's way more complicated than most, if not all, homeowners would know how to do. It's not like replacing a light bulb or plugging in a device to go to a web page with options that are easy to find and understand.
With DIY cluttering the marketplace, it's only a matter of time before end users find themselves spending too much time on automating their houses to get a lackluster experience compared to their neighbor's professionally installed system. That's already the case if the system is done right.
