I doubt it's that. Deletion is hard, but it's not "exactly 30 days" hard.

The most likely explanation is that OpenAI wants the ability to investigate abuse and / or publicly-made claims ("ChatGPT told my underage kid to <x>!" / "ChatGPT praised Hitler!"). If they delete chats right away, they're flying blind and you can claim anything you want.

Now, whether you should have a "delete" button that doesn't really delete stuff is another question.
