So tl;dr he/his team did two things:

1. argue the way AI uses content to train is legal

2. provide artists a tool to prevent their content being used to train AI without their permission

On the surface it sounds all good, but I can’t help but notice a future conflict of interest for Zhao should Glaze ever become monetized. If it were to be ruled illegal to train AI on content without permission, tools like Glaze would be essentially anti-theft devices, but while it remains legal to train AI this way, tools like Glaze stand to perhaps become necessary for artists to maintain the pre-AI status quo w/r/t how their work can be used and monetized.
