> For Linux, instead of downloading an installer, you pull it with a package manager, maybe go through some default settings, and maybe wait for the installer to finish.

You are assuming that the software in question is both packaged for the distribution you use and that it is available from the default servers for your package manager (and that the packaged version is recent-enough for your purposes).

The software installation landscape for Linux is a lot more complex than this, and for rather a lot of software, these assumptions break down.

Here are the Linux install pages for just a few examples of popular end-user applications that are actually available for Linux:

https://www.dropbox.com/install-linux

Snap and Flatpak promise to simplify the provision of binary installers for Linux so that developers don't have to create both a DEB and an RPM, much less an install script that has to be run as root, but that ends up pushing users even further away from the package manager, not closer.
