Package managers are a necessary evil on systems where installing software scatters a bunch of files all over because of a dogmatic adherence to an obsolete FHS. It’s a huge burden on either the distro maintainers or the developers to produce new packages for already-written software, which often results in outdated or broken releases available in the package repos.

And now every language ecosystem has one or more package managers for development libs - pip, conda, cargo, npm, opam, dub, etc. - and then optional package managers like choco, homebrew, and probably some others I missed. It’s a huge mess. So instead we throw up our hands and just bundle everything we need in a container and duplicate the _whole distro_ because the “package” ecosystem is such a disaster.

The sane way to handle software installs and uninstalls would have been cp/rm.
