This is a NEW stake pool. It doesn't touch the old stake pool.

The freedom account is not confirmed, but it does control the witnesses.

Those four are being singled out because they control 60% of Steem and the hardforks and what gets rewarded and they earned their stake in a poorly executed mine.

Since this is all NEWLY created the only point in doing it would be to experiment with how the site functions without that stake's influence.

Nothing regarding STEEM changes. (Except maybe people would rather invest in spork)
