As to windows software requiring admin to install. A lot of it comes down to that for the most part, software that installs globally should be limited to admin users. That doesn't mean that a lot of windows software can't install locally.

I do kind of wish that scoop used ~/AppData/Local/scoop instead of ~/scoop (from other comments). Looking into it more, it's interesting. I just didn't get a lot of insight from the home page in the post link. But I do agree with most of the troublesome issues with Chocolatey mentioned in this and other comments.
