"Still relevant"? Not to be a dick, uh, but who or what in that article was ever relevant? The author? jMonkeyEngine? Open source (for games)? Pretty sure the answer is a resounding no to all three.
That said game devs are pretty open when it comes to open source, kinda. Were it not for fear of patent lawsuits you'd see a lot more source code released. However our careers and livelihoods rely on copyright so you'd probably also see assets under lock and key like all the Doom/Quake releases.
