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... and while everyone is pretending they would never be afraid of an intern stealing their business, I doubt many of them saying that have been through this experience and know how it feels like running a business and trying to stay on top of all the scams and bullshit that will get in your way, including from previous "allies" like ex-employees who think can do better.

Just look at this from the other side: you employ lots of people to work on some product, you teach them "secrets of the trade", send them to conferences, let them participate in making decisions, giving them extraordinary insight in the area of work you are active on... and as soon as they leave your company, they use all that knowledge to try to create something with that on their own (I can understand it, once you konw stuff and enjoy it, you want to keep working on it even in your own time), just for fun... basically spreading some of that knowledge you gave them and making it packaged and accessible not only to future contributors of their project, but to all competitors and genuine copycats out there.

This is incredibly unprofessional. If he had at least come up with something original based on that knowledge , I would be totally on his side, but his stuff, while it may not be an exact copy of repl.it, is clearly doing the exact same thing... how is that not at least "stealing the idea"?? Just don't do that.

Show some respect to your ex-boss and collegues who are working hard for several years to get an idea out to the world and make it work for others as good as they can... if you want to use your knowledge, just contribute back to the project if it's open-source (your contribution will be a lot more useful, very likely, to other people than your poor, basic little project)! If you actually want to compete, which the author claims was not at all his goal (yeah, right, until someone shows even a trace of interest in paying something for it), then by all means go ahead and act reckless, but you'll need to come up with some pretty major advantage to have any chance, and will be taking pretty huge risks with lawsuits, but that's business as usual in the corporate world.
