I'd add the USA to that list - plenty of evidence that National Security Letters have been used to stifle/gain access to/alter coding projects in the interests of US GOV.

It's probably even more insidious, because simply confirming the existence of an NSL can be a crime punishable by significant custodial sentences. In the USA, posting "The police asked me to delete this code" could land in you federal pound you in the ass prison for 10+ years.
