An actual example is that the Python LSP extension on the offical marketplace has some "DRM" that makes it pop up a fatal "You can't use this extension except with the real VSCode" error message. People have been playing whack-a-mole with it by editing the obfuscated JS to remove that check, or by using an older version from before they added the check. https://github.com/VSCodium/vscodium/discussions/1641
