Most users who develop on Linux are not really Linux developers in the sense that we just write our own code and don’t contribute anything to the kernel, or to the userland programs that you were trying to use. The people who write the code you actually use are quite busy, so you usually just get random nobodies (myself included!) when you go online to chat about Linux. There’s some possibility that you might get help, because we happen to be using the same program, but that’s all there is to it.

If you want to know why VSCode is buggy, you will probably have to get into contact with Microsoft, I guess. I know this looks like some kind of smarmy sarcastic response, but it really is the truth; the rest of us really don’t know why they put bugs in there.
