I don't think they got an "appearance" fee but they sure were inticed to be there.  Benefits!!!!!  I don't think Tiger would have played this tournament without incentives.  And after Tom Watson makes the cut and makes a swipe at Tiger for missing the cut (TW) ( he did it indirectly) then I doubt Tiger will be back there.  He and TW have no love lost between them

The PGA does not allow 'Appearance Fees'

no they don't but incentives do not classify as appearance fees. 

There are ways around anything I guess

:-)

yes there is!!  LOLOL
