It's probably closer to releasing "open source blueprints" for a car (a steam engine is probably better) that explodes and kills it's occupants. Who is responsible for that? A better set of questions might be:
- Why does this person think they can release open source blueprints if they aren't qualified for what they design?
- Or, if a company used these blueprints to build a car, why didn't they do their due diligence?
