Yeah, honestly, this is pretty terrible.
I'm off to the US in January. Was already considering to cancel my reservations at Hilton when they announced that the food credit would be permanent in the US. Completely ..... This however, is one of the worse promotions we have seen the last years.
Earlier they at least had something in line with "2500 points per stay + 10 000 points every five stay". With the food credit and this promotion, I don't really see any incentive to be booking Hilton over other chains, when I am in the US.
