It is more about streamlined process of package management to which Linux users are used. At least with deb/rpm package I understand where package stuff goes and how to uninstall it (of course, packager could mess up this with arbitrary install scripts).
And each 'curl https://' packager has its own idea where his software should be installed. And many of them are not even providing automated way to delete their application.
