The Steemit INC stake is a special fund, just like @steem.dao is and should have had been coded with a special ruleset long time ago.

I fully agree with this assessment. This move could be taken as horribly aggressive since we are, after all, a dPoS system. However, SteemIt Inc's stake was never any old normal stake. This softfork is a result of the anomaly that is the SteemIt account & ownership. Anyone is free to come here with huge amounts of cash and act as a normal steem-citizen.
