If open$-$source software is free to use without licensing costs, what other factors should be considered when evaluating the total cost of operating such software? $2.$ Suppose JJ had a close friend who was a very experienced IDPS specialist, with broad and deep experience with a specific IDPS software vendor. JJ thought she would be an excellent candidate for the new position. JJ told her about the opportunity, but she was not quite as enthused about applying for it as JJ had hoped. You see, there was a referral bonus, and JJ would get a tidy sum of cash if she were hired based on his recommendation.JJ told her that she needed to get on board and that he would split the referral bonus with her. Do you think that is an ethical way to encourage the candidate to apply?
