IntelliJ simply could do C/C++ but they chose to push people towards a new IDE... C Lion. That was a huge blow for me, a polyglot.
Then I had a couple of bug opened with them... it took years for them to fix it. Except they marked it as fixed and it was indeed not fixed... Years later!
I kept paying until that point, I just couldn't do it anymore.
The company is a victim of its own success if you ask me. And that's a shame.
VSCode isn't perfect, but it does 90% of what IntelliJ does, and arguably 40% of it better. Also VSCode is faster which still boggles my mind as to how that's possible. I suppose the buttload of cash that Microsoft has thrown at it probably helps there... Since IntelliJ went through their "milliseconds latency blabla" years ago, it's gone downhill.
I imagine that retina pixel displays + java 2nd class child on the macOS platform = big oof (pre-metal).
I dream of a native vscode-like IDE...
