Not everyone is using a package manager for every install, and even then it's not a magic bullet. I'm a Mac user and I've no idea why devs insist on installing to places like /usr/local or putting configuration in a dot file in my home directory when there's a standard place to put those (~/Library/Application Support), among other well thought out directory structuring[1].

Further to this, the moment you want to install somewhere else or have a dependency elsewhere (e.g. /opt/anything) builds break because of hard coded paths and poor assumptions. To top it all, I've no idea why a package manager like Homebrew then contributes to all of this by acting like no of this matters because a Mac is just like Linux, apparently.

If they don't like Apple's way then why not XDG[2]? Reinventing the wheel badly is more than just hubris, it breaks things and it's annoying.
