Encryption is the first one that comes to mind, particularly since it ended up affecting consumers once the internet became commercialized. Anything remotely military related also fits into that basket, though few people would have run into the self-enforced hesitancy to release code since (outside of the military) it would affect very few people outside of academia. That said, the reality is that we live in a time that is very self-aware of the unintended consequences of technology as well as a time where we have communications technologies that propagate that awareness at a speed and breadth that were difficult to conceive of thirty years ago. This ranges from our impact on the environment to criminal activities online. I don't think that it is unusual for people to be questioning the unintended consequences of their work.
