For example, I know artists who are vehemently against DALL-E, Stable Diffusion, etc. and regard it as stealing, but they view Copilot and GPT-3 as merely useful tools. I also know software devs who are extremely excited about AI art and GPT-3 but are outraged by Copilot.
For myself, I am skeptical of intellectual property in the first place. I say go for it.
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.
