Any obfuscations Dash or BitShares try to claim won't help them escape culpability.
However I don't agree with ArticMine's claim that only the FinCEN has jurisdiction. FinCEN's jurisdiction is w.r.t. to money transmission, and the SEC has an orthogonal jurisdiction w.r.t. the Howey test for illegal unregistered investment securities (which was covered in detail upthread).
In order to pass the Howey test an necessary but not sufficient condition is the presence of a centralized administrator as per the FinCEN guidance. In short the virtual currency must be centralized and not de-centralized. This centralized administrator is needed to to provide the "depending solely on the efforts of a promoter or third party." part of the Howey test. There are already examples in decentralized virtual currencies where "depending solely on the efforts of a promoter or third party." part of the Howey test has failed. Bitcoin: the XT vs Core debate. Monero: Replacing the initial developer with the current team. Dashcoin (not to be confused with Dash): The developer "sold" the coin and the community simply ignored the sale and continued as if nothing had happened.
FinCEN guidance doesn't not apply to the Howey test. FinCEN is not tasked with protecting unsophisticated investors from fraud. FinCEN's job is to fight money laundering.
The Howey test is more nuanced than that, and if a group is promoting a coin for investment purposes they may be culpable under the Howey test. I covered this in detail upthread.
All cryptocoins that being primarily distributed to speculators with no significant users of the currency, are at risk IMHO. That includes Monero and Aeon.
FinCEN came down on Ripple for being an exchanger and a centralized administrator that was processing money transfers for third parties without registering as an MSB and applying AML/KYC controls. The sales of XRP for fiat that are violations are because Ripple was also exchanging and also able to remove supply from the market.
I don't see any mention of Ripple being in violation because of sales of coins it gained during the time of distribution whether it be premine or otherwise. The mention of the premine was just a statement of facts, not a statement of a violation. It is the fact that Ripple was acting as an exchanger and centralized administrator that tainted any sales of XRP they made.

In the statement of facts https://www.fincen.gov/news_room/nr/pdf/Ripple_Facts.pdf which is linked form the FinCEN page I quoted the following quote is very relevant. Bold my emphasis.

INTRODUCTION AND BACKGROUND
1.
Ripple Labs Inc. (“Ripple Labs”) is a corporation registered in Delaware and headquartered in San Francisco, California. NewCoin,
Inc. and OpenCoin, Inc. (“OpenCoin”) are the predecessors of Ripple Labs.
2.
Ripple Labs facilitated transfers of virtual currency and provided virtual currency exchange transaction services.
3.
The currency of the Ripple network, known as “XRP,” was pre-mined. In other words, unlike some other virtual currencies, XRP was fully generated prior to its
distribution. As of 2015, XRP is the second-largest cryptocurrency by market capitalization, after Bitcoin.
4.
XRP Fund II, LLC, a wholly-owned subsidiary of Ripple Labs, was incorporated in South Carolina on July 1, 2013. On July 2, 2014, XRP Fund II changed its name to
XRP II, LLC. During a portion of the relevant timeframe, the entity was named XRP Fund II, LLC, but it will be referred to as XRP II throughout this document.
Specifically, the Guidance defines an exchanger as a person or entity “engaged as a business in the exchange of virtual currency for real currency, funds, or other virtual currency.” The Guidance also defines an administrator of virtual currency as a person or entity “engaged as a business in issuing (putting into circulation) a virtual currency, and who has the authority to redeem (to withdraw from circulation) such virtual currency.”
Edit: I would not touch a pre-mine without legal advice.
