They got no insurance (Which is pretty cheap),...
I doubt you will find an insurance company that will make an insurance for bitcoin miner. If you start to explain them that they are extremely valuable devices that will be valuable for 3 months only though then they will send you out of office fast. Its simply a real nice risk. So i think it was unavoidable that no insurance was there. Or was there an insurance for the big mining farm that burned down some weeks ago?
Of course you can get insurance, I'm surprised you don't if you're mining on any sort of scale.
It doesn't matter that hashrate was provided by AM, the business agreement was still not signed by AM as a company only friedcat. Any funds available should in my opinion go towards wafers for a chance to resurrect AM or the company should be dissolved and funds distributed among shareholders.
*signed by friedcat in his official capacity as employee and CEO of AM?
