If that package was auto-installed, then it was brought in as a dependency of another package. Ultimately you can trace the dependency chain back to something that the user explicitly asked for. Maybe they later change their mind, and don’t want it. So you have “apt-get autoremove”, which will clean up everything that is not (directly or indirectly) a dependency of such an explicit installation. Thus, everything stays clean and tidy.

It's not a criticism. They have had years to fine tune and get it
right. Spent some time while back building packages for FreeBSD
Sparc and the build process is smart enough to know which other
packages need to be pulled in and built as well. In one case, Xvnc,
ended up pulling in around 50 other packages before finally building
Xvnc. Very impressive indeed...
