We have a few technologies in play in the world that operate on obscurity. Shared industry passwords like the DVD encryption key: https://en.wikipedia.org/wiki/AACS_encryption_key_controversy https://en.wikipedia.org/wiki/AACS_encryption_key_controvers... Even if it was technically a password, it's really obscurity because the password was literally available in billions of devices worldwide - it's just hard to read. Then someone figured it out (specifically in WinDVD). So, when someone says obscurity is fine, it's fun to remind them that all DVDs are cracked because someone thought so. (Not that I think that's a bad thing)
