"From the ChipIgnite program you can get bare die; from the Open MPW program, you can't. If you submit something on a ChipIgnite shuttle run, then the pads will be exposed, along with any other places on the chip that you place overglass cuts (i.e., you can place your own pad cuts internal to the user area)."
The other problem is that even for $10,000 the ChipIgnite program won't give you a confirmed booking. You have to submit your design and then they decide if they feel like manufacturing it. Any chip worth paying $10k to fab is going to involve an engineering sunk cost of around 5 times that amount. Which is why Real Fabs take your money and give you a confirmed booking.

The answer is actually nuanced.
