I don't think Wolfram will open source their engine, ever. Their income is mostly from selling the software licenses an I don't know how they could replace that income. However, it would be nice if they would open source parts of their application so bugs could be fixed in the user-facing parts. Even if their engine remains closed, the UI could be open sourced. I'm fine with them keeping their "secret sauce" proprietary and asking money for it. They spent decades making it work. I am saying this because Mathematica for Linux doesn't work great. It's violating the X11 protocols and doing some crazy things with XSendEvents, which makes it not work at all on some window managers (window layout is completely fucked, mouse clicks aren't received properly, etc), while other WMs (e.g. i3wm) have Mathematica-specific hacks to ignore some of the messages it's sending. I'm not sure what to do with this situation. For some of my projects (outside of paid work), I'd need Mathematica. So far I've used an educational site license for my university but now I've graduated and I won't have access to that. So I could pay them $130 (student license, I still have my @uni.edu email for now) to $300 (normal license) but I don't know if they'd fix the issue. I could start using a more mainstream desktop setup (KDE, Gnome, whatever) in the hopes that it works, but that's not ideal either. I have not contacted customer support because I'm skeptical that they would do anything for such a small minority of their customer base. Mathematica is almost the only closed source application I'd need. The open alternatives are not good enough and I'm not educated enough to improve them.
