Personally, I don't like it. Then again, I am not a marketing guy, but I will give my thoughts anyway.
First, I don't really see the value of the press release for the proposal. Let us first come to an official consensus on the merger with all of the details figured out before publishing anything that sounds official.
Second, AGS is just a ledger not a DAC, and I personally think calling PTS a DAC is even a stretch (although I guess it is just as much of a DAC as Bitcoin is).
Third, the voting mechanism (as far as I am aware) was on future hard forks for new functionality and changes on the hard caps for dilution. While I personally envision a future iteration of this voting mechanism to allow shareholders to vote on future mergers or even splits, I don't think the plan is to use a (yet to be developed?) voting mechanism to decide on this particular merger. As far as I am aware, I3 is the one that will facilitate this merger in a way that will hopefully not displease the community too much and prepare the hard fork clients that the BTSX delegates will hopefully accept and upgrade to.
This last point is the main reason why I do not like this press release. If AGS/PTS was part of a DPOS DAC with shareholder voting functionality, and this voting functionality was also added to BitShares X, and there was a common proposal on both blockchains with majority approval by respective shareholders for a particular merger, then I would feel comfortable calling this a merger between DACs. But with how the implementation of this "merger" appears to be planned (at least from my perspective), I believe the public response will be that this is nothing more special than just a complicated snapshot for a new DAC with a new token (BTS). Not to say that a properly worded press release describing the event after the fact wouldn't be beneficial (in particular the benefits of how it better unites the BitShares community and gives us a stronger network effect), but I am cautious of relating it to a merger of traditional companies when PTS/AGS do not have any board of directors (delegates) or even any mechanism for the "shareholders" to even vote on the decision.
