cherrybim:
Are you opposed to an employee opening a business in the same industry or opposed to stealing his former employers customer list? While the latter is wrong by anyone’s definition (and very rare in the frum community — even more so than outside) the former is quite common anywhere and nothing wrong with someone going into business on his own.
Michael Bloomberg is one such example. He worked for Merril Lynch before starting Bloomber L.P. Are you angry at him for competing with Merril after working there and Merril giving Bloomberg his industry knowledge? How is Bloomberg (and all the many like him) any different than what you complain of (assuming that is what you take issue with)?
