Bankrupt doesn't mean there is no money left. The receivers generally get first call on any remaining assets (otherwise who would be a receiver?).
The trustees are likely to be a large commercial law+accounting firm - they are a common target for lawsuits, since it's the only way for other lower ranked creditors to get any money back
Then there is the wholly unfounded suggestion that they might receive some lucrative business from another operating system vendor (through a couple of middlemen) to keep this whole circus going.
