I remember a specially egregious case that one of the rental companies was guilty of: automated criminality
The software in question automated the reporting of grand theft auto to authorities. The rental company used it to streamline reporting of rentals to police.
The problem: false positives. The software would report drivers as criminals, when in fact cars had been exchanged midrental due to car failures etc, and the original car hadnt been returned under the normal workflow, which the software failed to account for.
Then that police report would chase innocent people for literal years, coming up to unsuspecting customers during routine speeding stops.
I always wonder whether contributor names to closed sourced software should always be transparent.
Excellent engineers should be able to take credit on their work and there would be more skin in the game. Particularly for employers that get suspect resources from to solve for budget constrains artificially imposed by business managers with no stake in the product functionality, to critical software processes like SREs etc
