Why doesn't SiFive respond?

I only want to say that you have serious problems with PR (from my personal point of view). I don’t feel myself stupid when I look through Intel’s or ARM’s twitters. But when I see such a tweet I find myself a bit confused. A strange black guy, hm, is he CEO? Also, somehow I can get a quick answer from TI but I have to disturb Andrew Waterman via LinkedIn in order to get some answer after several requests via official channels.
