Not a joke: Microsoft's Copilot Terms of Use (https://www.microsoft.com/en-us/microsoft-copilot/for-individuals/termsofuse) assert that "Copilot is for entertainment purposes only." And they are charging HOW MUCH for this "entertainment" product?
@daviddlevine GPL-ed products also make clear in the license text that no guarantees are given, fitness for purpose included. But at least they don't babble about entertainment...
