Can we know for sure some of those folks didn't make those statements after being blackmailed by their record labels or some "interested party"?

The way I see it, people change their positions when:

a)they're blackmailed - either you stop endorsing that shit or you're history

b)they notice everyone else is on the other side and they switch so that they're on the winner's side - see some of the beloved politicians & companies (BSA, MS, etc) pulling the plug on their support of SOPA

It's pretty easy to blackmail a musician when you're the record label. You certainly have far more money than the musician and dying from an overdose happens in the world of the musicians; the death of the musician even helps the record label with sales, doesn't it?
