There was no drama as far as I recall, just complaints that he wasn't agile enough or something like that. The different project is Gogs https://gogs.io/ and its author is Joe Chen ('unknwon').
From what I recall the drama was that the split was timed to his absence and they announced everywhere that "Gogs is dead/unmaintained" until he came back and set the record straight.
The reason for the split was understandable, them going around proclaiming Gogs dead and unmaintained felt pretty scummy to me, however.
