Porsche has never been afraid to take advantage of the wealth of customers.

They started overcharging for accessories back in the longhood 911 days.

I may be mis-remembering here, but I recall that during development of the 918, Porsche was offering a "matching" Twin Turbo (something badge engineered and painted to compliment some of the 918's features) to customers who'd put down a deposit and wanted a bit of gratification before production began on their new supercar.

Cynical me, I just assume that buying a 150,000 dollar TT was a necessary expense of getting one of the first 918's.

To the OP, I'm sure the corporate heads at Porsche saw what Ferrari was getting away with and gave dealers free rein to follow suit - as long as AG gets to wet the corporate beak.
