Somewhat more charitably though it could be that it’s far easier to ensure you never train on something you don’t store.
The US Congress for example just purchased a bunch of licenses to start messing with ChatGPT at their offices.
That's probably just a dream and they just want to push you into keeping it on while they keep it for later just in case?
On the bright side this can be fixed with a client side extension :D
I've used this pattern in a few side projects. I never, ever have to worry about accidentally storing/moving/integrating data that doesn't exist.
They will still save all conversations. They are just pinky-promising they will not use it for further training and will remove it after 30 days.
But there is no way for us to verify that.
