It has been the smart economic decision for a decade or more already. Capitalistic greed caused some to spread FUD around that issue, deny there was a problem and attack several useful tools for dealing with it.

The fact that capitalistic greed has caught up with reality a decade later after most of the hard work was done and is now fighting on both sides of the issue is somewhat tragic.

Doubly so if you consider what it means about every other global problem we face that might affect a powerful incumbent's short term profits.
