The ridiculous ones are where it just sets up an apt repo - like someone can’t add a file with a line or two of text and run two very common commands (apt update/install).

Yes, that's good common sense. But you can check the source code on GitHub (it's deployed directly via GitHub Pages) or first download it and then execute without pipe from curl.
