Homework 8 In general, is it ethical for a CEO of a company to blog or post comments, especially the bad ones, about its rivals on a public forum anonymously? Or, is it perfectly fine because the CEO is exercising his/her freedom of speech? If this is the case, do you think the comments posted would be unbiased? Would they be qualified as "insider" information?
Homework 8 In the case of Whole Foods' CEO, he posted bad comments about its rival a week before Whole Foods announced to acquire it. Do you think he blogged for personal gain? The CEO of Whole Foods did not admitted he had done anything wrong at first, a week later, he apologized for what he did. Do you think he should be punished? Anything you could related to the 2 articles above.
