Some ideas on how it could work:
- Read through the connection data (phone,email etc) from key figures of the Bitcoin community to gain insider knowledge
- Infiltrate core development and replace Bitcoin key figures with NSA staff
- Discredit respected members of the community
- Kill people, if they don't corporate.
Are core devs discussing this possiblility of a large scale infiltration and how to avoid?
What if that infiltration has already happened?
Definitely more than just possible and my question still remains:
Are core devs discussing this possiblility of a large scale infiltration and how to avoid? (The answer is not related to any 51% theory or "destroying" Bitcoin, but to take control over Bitcoin development, edit: though the long time goal can indeed be to destroy Bitcoin "from inside".)
