If not, then it installs things into the operating system, essentially. ...this is only true for a Mac, where a third party comes in and opaquely modifies your entire filesystem with no accountability. On a linux distro the OS is upgraded through the package manager, so a userland install is not a needed feature. And Homebrew has a terrible track record with #2 as well. Certainly it's not going to beat any of the forementioned package managers.
