Just to sharpen your comment, here's the summary of that interaction with a shareholder:
[Cook] didn't stop there, however, as he looked directly at the NCPPR representative and said, "If you want me to do things only for ROI reasons, you should get out of this stock."
That's a very blunt statement that the immediate stock valuation is not Cook's only consideration.
Some people seem to have a hard time taking Cook at his word, but he's been quite consistent. This massive skepticism feels more like nostalgie de la boue than anything based in facts.
Compare to GE, which rolled over [2].
So I believe Mr Cook when he says his opposition to the FBI's request is rooted in a desire to do the right thing, and not the bottom line.
