No, this is not MIT. If you don't like MIT license then feel free to use something else, but you can't pretend this is open source and then attempt to slap on additional restrictions on how the code can be used.
Which, if you think the weights are copyright-able in the first place, makes them practically unusable for anything commercial/that you might get sued over because relying on a vague implicit license is definitely not a good idea.
What bugs me overall is that it's usually vapid mimicry of a phrase they don't even understand.
The wording they currently use suggests that this additional license requirement applies not only to their pre-trained models.
