> Agreed... but the intern is obviously incredibly naive in thinking that repl.it would be happy to see one of their ex-interns working on a project that does pretty much the same kind of thing they're doing.. whether or not this is a threat to them right now. There's a tiny, but non-zero chance, that this project could become successful and who knows, take marketshare from repl.it...

Too bad, that's business and how a functioning free market works. If it's that important to Replit, then they should patent it. If they can't get a patent then, again, too bad.
