Honestly, I doubt most people even care it's kind-of open source (1).
> 1. Free
This is the reason most people use vscode.
That's it.
It's free, and it's pretty good.
It's not better. It's just free.
Nothing wrong with liking free stuff; free stuff is great; but don't confuse 'it didn't cost me anything' with 'it's good'.
There's a difference between value (ie. for what you paid, you got something that was worth significantly more than you paid, which in this case is zero) and quality (independent of cost, the thing is just plain old good).
vscode may be more valuable to people than jetbrains products, but it isn't a higher quality product.
There's a massive difference between those two things.
