This is not a slip up-it’s basically malpractice.
No idea what the legal precedent for negligent software engineering would be…
I suppose it depends what you consider agreement to social rules and how you define liability. I can certainly be held liable for damages for my actions to others which do not require me to hold any license - merely break the law.
Did I agree to the “rules of the road” when I was born? Do I consent by not emigrating?
