Even if they fire Ephrem's ass, an executive at his level probably had a sweet, sweet termination clause in his contract, and likely wasn't relying on his salary for much of his income anyway. Plus, dudes like that usually land on their feet, and "forced out by Wedge affiliated hippies" has a lot of cachet in certain sectors of the corporate world, I understand.
I suppose Juri could have made Genom using its clout to blacklist him industrywide a condition of the sale, I guess. Larry isn't above that sort of deal.
