As I said in the other reply, my post is at an emotional/personal level (as an owner/creator and also employer), not necessarily a legal or more political one. On that basis i 100% side with the author here.
I was merely saying this situation definitely smells like one where there's more to the story than "big bad replit picking on poor innocent open source guy". Just the tone of his writing seems, and the "one of most difficult interns" gives me gut reaction that he might actually be someone who tries to be pushy while being nice.
