according to michael olliffe, who posted numerous rants on the subject back when .net was still in existence, dave was never so much upset with craig as he was patrick and vines mgmt. according to him, craig had wanted to keep dave in the band (probably to do with not liking change?), but it was patrick and mgmt who pushed to get him out. there was very bad blood between dave and patrick for some time, because dave felt he'd been betrayed by an old friend, and both were guilty of saying very nasty things about the other.
in regards to craig, michael always said craig seemed wrapped up in himself (well, now we understand that a little better), and the olliffes didn't really fault him for what happened.
i'm just glad things have worked out for all their sakes. time, distance and perspective can help with that.
