There are also a lot of links to news in the media. I didn’t check every link, but they will probably lead to the explanation I still remember, that the developers moved from OwnCloud and created Nextcloud because they were no longer happy with the direction OwnCloud was heading. It was lacking transparency and was too much focused on business customers leaving the community behind - if I recall the developers comments correctly.
After these news however I joined the Nextcloud community instantly
You are very welcome, too!
