If that’s the case, it’s a bit of an ugly hack but you could make a wrapper script placed in /usr/local/bin/inkscape like this:

#!/bin/bash

flatpack run org.inkscape.Inkscape ${*}

(the ${*} will pass along all the arguments that the wrapper script was called with)

For me, they’d have to

1. Replace /u/spez
2. Implement some sort of publicly auditable accountability re: shadowbans and database-level comment editing
3. Open-source significant parts of their platform.

I have zero expectation that any of these things will happen. The most healthy way forward, for an open and free internet, is the meritocracy of the fediverse.
