What Happened to Lum Tec?

I’ve been following Lum Tec for years. Local company to me. 
For years, it seemed there were articles/blogs about their stuff all the time. Now, I never see anything written about them. 
 

Has Lum Tec become boring?  Are they out of date?

Whats everyone’s opinion of them?

I see plenty written on various fora. Just too big for me.
