It's not stopping to give legal/medical advice to the user, but it's forbidden to use ChatGPT to pose as an advisor giving advice to others: https://www.tomsguide.com/ai/chatgpt/chatgpt-will-still-offe...

Good. Now we just need to add technical advice to the list of advices which ChatGPT cannot be used to cite for

This. I already seen too many cases of people wiping out their systems while trying to follow invalid advices from ChatGPT.

One wonders how exactly this will be enforced.

It's not about enforcing this, it's about OpenAI having their asses covered. The blame is now clearly on the user's side.

It’s a “CYA” aka don’t sue me

It was already enforced by hiding all custom GPTs that offered medical advice.

The Tom's Guide article blatantly misinterprets and contradicts the source it quotes.
