> I expect OSS to go the opposite direction: no human contribution allowed.

How is it an incorrect interpretation? Jared is indeed pitching/suggesting/predicting that human contribution will not be allowed in the near future, i.e. banned.

"Pitching" generally means that the person making the pitch is endorsing and pushing for it. (This might also be a regional word meaning/usage difference type thing.)

The person upthread should have said "predicting".

A prediction is not a policy.
