Earlier quoted context omitted.
That quote seems more like political-speak than actual hard numbers. The article also said that the state government gave Apple $46 million in tax breaks, while local government cut their property taxes by 50 percent and personal taxes by 85 percent. I'm hard-pressed to see how the taxpayers aren't subsidizing this datacenter.
They gave Apple those breaks to get them to build the facility there. No breaks 0 revenue, breaks some other > 0 revenue.
Money is fungible; tax breaks are no different in function than charging the full tax rate but handing Apple a pile of cash equivalent to what they'd have saved with the tax break.
It's a subsidy. The argument that they made more with the subsidy than they would have without it is separate from the idea that tax breaks don't amount to a subsidy (which was yummyfajitas assertion).
