People who withdrew will not be getting their plot for free.

SE said quite specifically they are still deciding what to do, it could be as simple as a dialog we had with FCFS when you won, pay $45,000,000 to purchase this plot". They have the code for this already after all, we used it for years.

The people who spent their refund though, will likely be out of luck, as they can't pay the money, they will need to forfeit their win.

But, I am quite certain there won't be any free housing. That's just a whole pile of butt-hurt and salt waiting to happen.
