In 19.04 I had removed all of the snap applications, and installed regular code versions of these same applications.
I upgraded to 19.10 and it reinstalled all of the same snap applications! This can be seen as the various /dev/loop[1-8] devices...

Any idea why Ubuntu insists on (re)installing snap applications? Don't they delay boot times? What makes these snap applications better?
