Oh, I think I understand now.
You say that Amazon does not expect to sell many DXG from now on, so there's no plan to invest on it, and in the meanwhile previous buyers can go to hell
. I could agree.
Still it seems contradictory as strategy: they could empty their stocks by cuttin heavily the price. At 200 dollars they would sell again a lot of these.
Since Amazon is highly trusted, a good firmware improvement could result in a boost for sells.
