Apples and oranges.

Package managers only install a package with defaults. These helper scripts are designed to take the user through a final config that isn’t provided by the package defaults.

Whether there’s a setup wizard doesn’t have anything to do with whether the tool comes from a package manager or not. Run “apt install ddclient”, for example, it’ll immediately guide you through all configuration steps for the program instead of just dumping a binary and some config text files in /etc/.

So that’s not the bottleneck or contradiction here. It’s just very unfortunate that setup wizards are not very popular as soon as you leave Windows and OSX ecosystems.

There’s literally no good reason to replace it with a shell script on a website.

I fully agree that a package manager repository with all those tools would be preferable, but it doesn’t exist, does it? I mean… content is king. If the only way to get a certain program or functionality is a shell script on a website, then of course that’s what is going to be used.
