I understand the feeling of being taken advantage of, but this seemed clearly like an over-reaction. A 100% apology was in order from my (sideline) opinion. He's just an ex intern having some fun, probably trying to impress his former boss even.
I was reading through the replit blog to see what kind of things are trade secret vs public, and noticed that they didn't go out of their way to highlight that Bret Victor's "Learnable Programming" is clearly the complete inspiration for replit's debugger (time travel, no hidden state, etc). They have a small link to Bret's work but don't mention him by name. Considering Bret's article is basically THE piece to read w.r.t. programming environments, and the gif that replit shows looks pretty identical, it seems right to have his name/article clearly at the top.
