I agree the interaction could have gone more smoothly. I also still think Repl.it and Amjad have reasonable viewpoints. I didn't see a panicky or instant legal threat reply from the emails. I saw an email pointing out the copying issue clearly, then a strong and lengthy pushback email from Riju author, and _then_ a reply about lawyers. The "I did nothing wrong" email from Riju author probably seemed benign, but seemed like strong pushback from Amjad.
