I like how the letter implies that Bloch should have put up higher fences to ease the training burden on the company. Last time I checked that wasn't part of his job description. I know it's highly unlikely, but for all they know the three merger committees could have come to an agreement outside of arbitration.
He should just come out and say that the management team who signed the contract (including our current COO) couldn't see the forest for the trees.
Gotta love this industry.
