Totally agree that MS deserves criticism as you correctly point out. However, criticism towards the script and similar is equally valid (and important).
I've seen some opinions, but none could be objectively evaluated as really pointing out problematic settings. They were more in the area of subjective preferences.
But this is exactly the point behind the criticism. The script is presented as “run this to make Windows better/safer”. If you did that without evaluating and understanding these subjective preferences, you might end up in a worse state than you started in, because maybe some of those preferences don’t really match your needs.
But even if the house is made of poo, shooting holes in the wall is not the way to fix it.
There really aren’t any winning moves other than not to play at all. Which may be an insane self sacrificing position.
