I'd love to see his original letter. What prompted him to whinge about them in the first place?
SA goons really hate Bitcoin, think it's a scam, see it's users as lunatic idiots, think only use for bitcoin is illegal activities and scamming people, and they desperately want bitcoin to fail just to get some laughs at others' expence. In other words, they're a bunch of bored lonely trolls with a glorified sence of justice, and way way way too much free time on their hands. So that's why.
If they really though this they would not pay any attention to Bitcoin. Its because they believe it can take off that they are so obsessed.
