I think Apple realised that they weren't fighting Proview, they were fighting the Government. Proview's liquidators only asked for what they owed to clear the debts.
As the debts were mostly owed to the banks, it was in the Government's (and therefore the court's) interest for Proview to get a good result.
The banks will have written that money off long ago so they'll be happy with the result.
At least Apple now know how s*** goes down in China now, they won't...
