Today, US based file sync & share vendor Kiteworks announced their acquisition of ownCloud and Dracoon. Nextcloud offers a free hands on migration service and takes over the remaining runtime of the contracts. Migration is a very quick and easy process, as shown by the many hundreds that have done this already over the last years.

So at least they are saying owncloud and ocis will still be maintained and keep their apache licenses… Still, acquisition of open source software is always a bit scary.
