I can say as a dev who's done Govt. contracts for a long time, vendors absolutely let code out the door with shoddy testing like, a disturbing amount across the board, and have issues make it to production. I've never seen anything quite like it in the private sector.

That said, as we all know, this flipping stuff sure as shit wasn't a bug! Bugs break functionality, not create convenient side-effects to help very specific use cases.
