He made millions off the app? Okay, so? Reddit makes more off of user data they don’t even make, then gets mad when people make a better app than them or another large company decides to scrape the data that isn’t even their’s. If he made millions as you claim in your complaint about white knighters, he probably made millions because people really liked his app.

Also, no-one is obligated to open-source their code. It’s their choice if they wish to or not. Yeah, it might suck, but it’s not the end of the world, and that sort of entitled behaviour only pushes away the people who could potentially open-source their code. I’ve fell into that trap too.
