fake > what relevance is there to whether the corporation is Jewish?
of course, it does. We have commandments and we are also enabling kiddush/hillul Hashem by our actions. Now, if you are a CEO of a public corporation, then you have a contract with the shareholder to maximize their value. So, if you want to be meshurat hadin, you would need agreement of the Board.
There was, I think, a textile factory in the 1990s with a frum owner that paid his workers for many months after his factory burnt and also rebuilt the factory – that generated a lot of kiddush Hashem with the press. All Jews in business are observed by others, sometimes with ayn tov, sometimes rah.
