The difference I see between a company dealing with this as opposed to an open source community dealing with this is that the company can fire employees as a reactive punishment. Drive-by open source contributions cost very little to lob over and can come from a wide variety of people you don't have much leverage over, so maintainers end up making these specific policies to prevent them from having to react to the thousandth person who used "The AI did it" as an excuse.

When you shout "use AI or else!" from a megaphone, don't expect everyone to interpret it perfectly. Especially when you didn't actually understand what you were saying in the first place.
