I believe the word SCAM is appropriate because SmartCoins continue to be advertised with the settlement guarantee, which is no longer in place for bitCNY, and will soon cease to exist for bitUSD (and most likely others).

The attitude of the committee (including your label "fine tuning of an experiment") show complete lack of respect for other people's property. IMO that's catastrophic for a blockchain that ultimately tries to sell trust.

All market pegged assets (aka SmartCoins or MPA) in BitShares are affected by the underlying problem, i. e. the issuer can modify crucial parameters after the fact. In that regard, MPAs created by individuals are even more vulnerable, in the sense that committee-owner assets cannot be modified at the whim of an individual.
