My bad. I actually meant agpl. And gpl. You're right to point out the that mit is fine. Which is true. Mit can be used for whatever.

But my for example my WineGUI project is agpl. Pretty sure those Ai companies used all open source code regardless of the license.

I'm actually also fine if they trained on my agpl code. But then they should have open sourced their models and data. And their whole project.
