What Sokol did (buy a stock first, then pitch the idea to Buffett without disclosing his holdings) is self-serving and reprehensible. Especially considering how petty the amount of gain (3 million) was, compared to his net worth (in hundreds of millions) which means it was more about the chutzpah and arrogance than the unjust enrichment aspect that was more alluring to him.
One would think he would come to his senses by apologizing and make amends with his former boss, not just because it's right, but because it would lessen the damage this entire debacle has caused on his reputation. Belittling someone as influential and respected as WEB publicly (whether justified or not) is just digging your own grave IMO simply because in the public's eye, WEB has accomplished more in his lifetime than 100's of Sokols can ever dream about accomplishing.
