But to be honest if your code is open source im pretty sure Microsoft don't care about licence they'll just use it cause "reasons" same about stable diffusion they don't give a fuk about data if its in internet they'll use it so its topic that probably will be regulated in few years.
Until then lets hope they'll get milked (both Microsoft and NovelAI) for illegal content usage and I srsly hope at least few layers will try milking it asap especially NovelAI which illegally usage a lot of copyrighted art in the training data.
