If this is correct, what was his motivation? I fail to see what he could have gained from it, other than a few extra billion in revenue, which they likely would have made otherwise anyway.
You don't become a billionaire by leaving money on the table. Achieving this kind of wealth is proof that you will never be satisfied, the reasonable people took their exit a while ago and are enjoying themselves peacefully. You most likely already took shortcuts and illegal actions to get there, so why not continue in that direction?
