community.
Karlitschek and many of these contributors went on to fork the ownCloud, creating NextCloud.
The fork was preceded by a blog post of Karlitschek announcing his departure and raising questions about the management of the ownCloud, its community, and priorities between growth, money, and sustainability.
There have been no official statements about the reason for the fork. However, Karlitschek mentioned the fork several times in a talk at the 2018

Following American law, we are forced to close the doors of ownCloud, Inc. with immediate effect and terminate the contracts of 8 employees." ownCloud Inc. accused Karlitschek of poaching developers, while Nextcloud developers such as Arthur Schiwon stated that he "decided to quit because not everything in the ownCloud Inc. company world evolved as I imagined".
