There is no "three-to-one" margin. You don't get to claim agnostic/DGAF as votes to affirm your silly fork, which actually only enjoys 60% support against the negative/status quo default presumption.
His math is correct though, if you have 60% X and 20% Y then you have a 3-to-1 ratio
The math is correct, but it's 60% pro and 40% not-pro. So 3:2. Not remotely close to even rough, much less sipa's extremely wide, consensus.
I don't know why you assume that agnostic/DGAF should be on the anti side. If I wanted, I could arrange the numbers this way:
Anti: 20%
Not-anti: 80%
It makes as much sense as 60% vs 40%. That is, no sense at all.
