I guess that's where the rage comes from. People that believe a policy is without reason.

I said at face value because there was no reason given in either the policy nor the article submitted here.

It would be interesting to know why they decided for a general prohibition, rather than going with the default "a human must be responsible for the contribution" kind of policy.

Perhaps they have received a flood of undesirable AI generated contributions, and actual contributors do not use AI significantly.
