I think people with this kind of integrity are very few in general. Being HN participant does not really increase the chances. Might even be the other way around as being smart asses it is easier for us to come up with the reason to keep our conscience quiet.

I do not think it has anything to do with "move fast and break things" way of doing things though. You can't expect the same approach and investment in safety in generic company vs some nuclear power plant or likes.
