That’s because you’re using something those companies officially support. Is your argument everyone running Linux needs to be on a Debian-based or Fedora-based distribution?
Btw the official “vscode on Linux” instructions literally point to the community maintained AUR (same for nix).
The truth of the matter is the AUR is poorly maintained structurally, regardless of what companies officially support. Things like letting arbitrary people unilaterally take over orphaned packages is horrendously stupid.
Stupid or rather low-friction on purpose?
Both. And that's an even worse combo, making stupidity frictionless.
