I also didn't know anything about them until hearing about the shutdown but now that you mention it I have seen the "Wink" stuff in Home Depot and probably elsewhere. However that was negative signaling for me, since Home Depot is not a name that I trust for tech but just a place I go if there isn't time to order something. With Nest products however it was because I had heard of them long before seeing them in Home Depot that my reaction was neutral-positive for retail stores carrying them. I don't expect my jaded 20-something outlook to represents most shoppers but it would've been cool to know about.
