The only activities where deleting is disabled are pre-installed ones. The
ones you install should be able to be deleted. If not, this is a bug.

Regarding the decision to make pre-installed activities permanent, it is
driven by Sugar deployments: teachers requested that certain activities
always be available. Which ones is a deployment x deployment decision. For
SoaS, we have a very limited set of pre-installed activities, but as the
Fedora image grows, the user-space shrinks.

FWIW, from the Terminal Activity, you can delete the pre-loaded activities
in /usr/share/sugar
