Overlaying morality on top of bitcoin doesn't make it more resilient to attack.

When government-run water supplies run low, fines and invective are used to punish and embarrass those who might water their lawns or wash their cars. A free market solution is to simply raise the price of water - incentivising conservation. It sounds like that's what the miners have done (de-prioritizing SD txs). Berating SD doesn't seem to have accomplished anything.

Satoshi Dice has helped make it clear how easy it is to bloat the blockchain. If that slows adoption today, that's fine. Slow and steady growth is better than the boom and bust of publicity and exposed-flaw.

Lastly, it sounds like they're filling a market need. Apparently lots of people are "rolling the dice" because they want to. This is what P2P transactions are supposed to be about. No one should be able to stop anyone from sending bitcoin to anyone. This scenario was possible ever since the genesis block. If we've got a "tragedy of the commons" in the blockchain, then we've got to solve it in the model of P2P - not by name-calling.
