Some recommendations:
- Improve communication to the users regarding the limitation of the snap distribution via Inform users with custom dialogs , this mitigates the concern of reputation damage when user found they can’t achieve certain goals using this type of the distribution.
- You can package and distribute snaps in classic confinement via external channels like GitHub releases. Just note that in this case the snap can’t be automatically updated so you need to implement update checking logic to tell the user whenever a new release of the application is available.
- Investigate the possibility of allowing arbitrary file access via the XDG Desktop Portal mechanism, the difficulty of make use of this mechanism depends on the tech stack of your app.
- You can also consider distributing you application via Flatpak, which do allow the users to manually override access confinement to certain paths.
- Verify your facts before responding; unsubstantiated claims will only undermine your position.
