I have a feeling that this is going to go similarly to Stable Diffusion's big 2.0 flop. SD put its limits in through training data. Meta put in its limits via terms and conditions. The end result for both will still be that the community gravitates toward what is usable with the most freedom attached to it. The most annoying part of the TOS is that you can't use the output to improve other models.
Fuck you Meta, I wanna make a zillion baby specialist models.
