> OpenCloud is the "open-source" fork but they are already in legal trouble with OwnCloud due to industrial espionage claims.

Can you expand on this or source this? I'm quite interested in OpenCloud, and haven't heard anything about this. I searched for a few keywords (espionage, legal, lawsuit), which only lands your comment on top.

Sure. I didn't say exactly lawsuit because my source only says a threat from Kiteworks (parent company of OwnCloud):

They seem to avoid openly discussing and comparing products to avoid further action. Apparently some of the former members of OwnCloud have switch to Heinlein (maker of OpenCloud) and Kiteworks isn't happy about this.
