Just read that OwnCloud closes http://fortune.com/2016/06/03/what-happened-to-owncloud/ , continues on Germany only https://owncloud.com/de/ , a foundation is created https://owncloud.com/owncloud-announces-formation-owncloud-foundation/ and a fork happens: Nextcloud http://www.silicon.de/41627901/ehemaliger-owncloud-cto-karlitschek-hat-fork-nextcloud-gegruendet/ . I'm a happy user with a personal instance.
