I’ve been looking at the rewrite of Owncloud, but unfortunately I really do need either SMB or SFTP for one of the most critical storage mounts in my setup.
I don’t particularly feel like giving Owncloud a win either, they’ve not been behaving in a particularly friendly manner for the community, and their track record with open core isn’t particularly good, so I really don’t want to end up with a decent product that then steadily mutilates itself to try and squeeze money out of me.
The Owncloud team actually had a stand at FOSDEM a couple of years back, right across from the Nextcloud team, and they really didn’t give me much confidence in the project after chatting with them. I’ve since heard that they’re apparently not going to be allowed to return again either, due to how poorly they handled it.
