A healthy, competitive reponse to a single former intern one-upping you would be something among the lines of "ok, kid see if you can replicate THIS".

Also a healthy response would be to issue a C&D - assuming they have a case here.

But this? We don't have all the details and Replit might well be in the right here, but still - that's not how you handle such cases.

And I should know, because I've been in trouble regarding my comments on HN with a company I used to work for, but the communication on their side was firm, polite and professional.
