I am pretty sure they get updated just like Windows and OS X binaries,
but the tar ball should be extracted in a user writable location

nonsense

*if* you use binary tarballs they *should not* be extracted in a user writeable location as *no binary* whenever possible should have permissions allowing a ordinary user to change them

they should be extracted to /usr/local/ with root-only write-permissions and you have to just start the application as root for updates - not only on Linux, on *any* operating system

and since most users are not able to cope with this security principals package managers exists

World-writable files, particularly system files, can be a security hole if a cracker gains access to your system and modifies them. Additionally, world-writable directories are dangerous, since they allow a cracker to add or delete files as he wishes
