The author does address the subjectivity of the integrity dollar value:

""The $I cost is the most subjective of the four and depends on how much stock a player puts in "doing the right thing," (so to speak) or whether they even see any moral integrity in the choice at all.""

I agree on the value-added point though, there are often services game makers can provide which make the official copy more attractive to players.
