Okay yes I remember that. It seemed at the time Bitshares was going through a lot of turmoil, which included seeking alternate sources of funding such as building custom systems for banks (not clear that they ever got any takers). I still don't know the details of it, but it seems that project model has not worked out very well ultimately, just as I said at the time. It appears that Dan sold his remaining coins at a much-reduced price and moved on, though it isn't entirely clear whether he may contribute to it in some manner in the future. All in all I can't see how that is called a great success of a project; you might disagree.
Although perhaps an accurate summary of some facets and appreciably sobering, I think this is indicative of too pessimistic or one-sided perspective which needs more balance.
He may have profited earlier during the ProtoShares, which may have kept him motivated to keep trying...
A better summary of what Dan was going through during that period and I specifically saw his frustration for the few moments I was in his forum:
