It's absolutely insane that Debian would remove /var/lib/docker when uninstalling Docker.
Debian is a free operating system (OS) for your computer. An operating system is the set of basic programs and utilities that make your computer run. Debian provides more than a pure OS: it comes with over 59000 packages, precompiled software bundled up in a nice format for easy installation on your machine.

To be fair, I was purging. That is supposed to remove all remnants of a package. Trouble arises when another package is still using those remnants.
