The point wasn't "Oracle", it was "program with a shitty installer". Pick any program with a shitty installer and substitute at your leisure. There are plenty of educational titles that would fit in its place, in my experience.

And I'm not defending what you seem to think I'm defending. If you want to talk about how crappy the Debian system is, fine, I'll defend that. However, what you're railing against - "desktop Linux" - doesn't exist. I don't need to fix anything; the installer on my system Works Just Fine. That it isn't the same mechanism as your system doesn't matter; it still works.

As far as I'm concerned, installation is a solved problem. There are other issues that are barriers to adoption. Software installation just isn't one of them.
