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.
I like it for all the apps. I got a cookbook app, forms app, rss feeder app, and more. It also lers me share a link to a file easily too. I also use syncthing, mostly since I sync more data than my VPS serving nextcloud can store.
