This is definitely good news (if it is what I understand to be a single one time downvote for each enrolment) , SBI is a great way for much smaller accounts to help each other out and puts Steem aside for a long time (and off the selling market), encouraging longer term thinking for participating accounts. Short term speculation and profiteering is what drives down prices and the quality of the chain.
SBI has been one of the oldest and most forward looking projects supporting the smaller end of town, long before #newsteem made it fashionable.
A small downvote is something I am willing to absorb too help smaller accounts and worthwhile projects like @pifc.
