I believe that one minor reason is the PKP chokehold on public-key patents. It has slowed down adoption within the US, and the RSA licenses for example tend to get very "interesting" when it involves places where their patents don't hold. Last year, how many COTS products had strong crypto? There are very few software imports into the US. I don't think crypto is particularly slighted. There might be pressure, and there might be dummy front firms, but with tongue in cheek to emphasize the point, I just think those ferriners can't code fer shit. /r$
