This is a false representation of what Bitcoin Unlimited actually does which is to hand over all of the power to mining nodes.
No it is not. It does not hand over all the power to mining nodes. Please stop being so stupid - we know you are smarter than that.
In effect, BU removes any power the individual, independent users might've had.
In effect, it does no such thing. It does the exact opposite. It strives to return an equilibrium among all stakeholders.
It does.
It pretends to use signalling from nodes to create your pretended equilibrium but this is easily skewed by a sybil attack.
Miners are then left to pick a number while unable to discern between legitimate nodes and the sybil attacker.
