I understand your concerns regarding my first post, but this has nothing to do with the problem itself.
I wonder wy this is not owncloud. The MCU tactic is exactly the same, they circumvent the AGPL. Sadly i read this article : https://karlitschek.de/2016/04/big-changes-i-am-leaving-owncloud-inc-today/ in 2016 and it seams more and more that i missunderstood Frank there.
But this is going to be hardly offtopic and does not reflect the time spend on writing anything here.
Have a great time and stay healthy.
