It's wild and, while they're all guilty, Gemini is a particularly egregious offender. What really surprises me is that they don't even consider it a bug if you can predictably get it to generate copyrighted content. These types of exploits are out of scope of their bug bounty program and they suggest the end user file a ticket whenever they encounter such issues (i.e. they're just saying YOLO until there's case law).
