Sorry to hear that, as my goal was to make it easy an intuitive for novice users 
I have been considering how to support the project by having another business that has goals aligned with a working open-source Duplicati project, and have many ideas. But in the end, starting any business requires a significant risk-taking, and I have not been confident enough to take that jump so far.
It is fairly common for open-source projects without a “sponsor” to have periods of low activity. If someone wants to sponsor the project, or commit to specific tasks, send me or one of the moderators a PM.
I still hope that I will be able to resume my Duplicati work, but my current situation does not have room for this.
