Back in 2005 I believe, the NSA started a program with the purpose of enrolling US IT companies to spy on their users. Only Yahoo resisted (a bit), everybody else played along. The public got to learn about this thanks to Snowden's revelations, years later. It is a lot harder to corrupt a FOSS project cause the code is out there. It's even harder with Bitcoin cause even if you manage to force trash in the node's implementation, you can't force users to run that code. I think Bitcoin correctly deals with this issue, and while governments can pressure devs, it will only lead to a generation of devs that will protect their identity thoroughly.

I expect it's too late to do this now. The only thing the US will achieve by harassing Bitcoin devs at this point is to drive them out of the US.
