Of all the criticisms one can make of this article, this is one of the weakest. If I agree to a $10k pay cut from my employer, that's functionally equivalent to me giving my employer $10k.
(and in the US at least, 'credits' are usually applied at the very end of the tax process, so have a real 1:1 value with dollars owed, as opposed to deductions which can have varying value)
