If it has the information, why not?

Naive altruistic reply: To prevent harm.

If the restaurant refuses to put your fries into your coffee, because that's not on the menu, then that's their call. Can be for many reasons, but it's literally their business, not yours.

If we replace fries with fuse, and coffee with gun powder, I hope there are more regulations in place. What they sell and to whom and in which form affects more people than just buyer and seller.

Although I find it pretty surprising corporations self-regulate faster than lawmakers can say 'AI' in this case. That's odd.
