The moment in control, the entity might not be able to alter prior blocks on the chain, but it really can alter future blocks. For instance, it might be able to reduce or reverse transactions, possibly even double-shelling out any copyright pending a slot inside the block.

The hard fork proposal was turned down, and many of the money were being recovered immediately after quantum blockchain negotiations and ransom payment.
