Boingboing writer Cory Doctorow recently posted an article about the Starforce copy protection malware. Earlier today he received a threat from Dennis Zhidkov of the company in question.

I just wonder, what happened to free speech? Is it free speech as long as it is not uncomfortable?

Update: Boycott Starforce (digg it)
