I know for a fact that the witnesses have zero intention and will never remove SBDs unless a large enough population mobilizes against them which I don't see happening.

As for investors pulling out of Steem if SBD's plummet back towards $1, that might not be a bad thing. It helps to reset the market and return things to normalcy. It also helps to remove some of the short-term profit driven investors. It's not really our responsibility to make sure that they do their due diligence and research their investment by reading whitepapers and understanding the mechanisms behind different currencies on the blockchain.
