I agree about the tone, but I think it comes from youthful inexperience and a lack of (legal) knowledge. OP has no idea where the line is, what the lines are, or what professional legal defense would actually require/entail. And so they're stuck trying to rationalize every possibly-defensible point in the court of public opinion.

Also, a good way to get employees that aren't testing boundaries is to hire experienced developers rather than interns who are still learning the world.

Overall I don't see what leg repl.it has to stand on here - their product relies on taking numerous free software packages and bundling them into proprietary software, and yet they have the gall to consider button placement some secret sauce?! But it also depends on what OP's employment contract says and when he actually developed this. Altogether, this really just looks like a case of a CEO personally bullying someone else because they can.
