That's not being fair at all. To say the only reason he is doing it is to protect iPhone sales doesn't speak to Tim's character. Of course he cares about sales, but he also cares about privacy.
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.

[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.
We should be careful about plainly stating what someone else's motivations are when it contradicts their own story.
Edit: s/it's/his reasons include/ for clarification.
We still live in a world where all people are not treated equally. Too many people do not feel free to practice their religion or express their opinion or love who they choose. A world in which that information can make a difference between life and death. If those of us in positions of responsibility fail to do everything in our power to protect the right of privacy, we risk something far more valuable than money. We risk our way of life.

Cook's responsibility is first and foremost to the stockholders, and secondarily to the customers. Decrypting the iPhone would seriously compromise the security of Apple's products, gravely damage the company's credibility, hurt sales, and drive the stock price down.
No CEO is going to take such a drastic step unless they are a craven, cowardly type who meekly obeys ask-for-the-sky demands from overbearing federal law enforcement types, and Cook surely did not rise to his current position by being a pushover.
That's not to say there won't be some kind of secret deal made behind closed doors, but secrets tend to get out. Apple would not be so foolish, I think. Yahoo? Microsoft? They just handed over the keys to their email to anyone who demanded it -- the Chinese government, the NSA -- but Apple has no history of this type of behavior. Surely Snowden would have revealed it if they had.
People that really care about security don't use smartphones.
I'm not sure this is true once you factor in price range. The general knowledge is a lot of those Android devices are sub-$250.
Maybe by share of units shipped. By revenue share they dominate, and their margins are estimated to be very good.
So?
I understand wanting to know people's motivations, from both the perspective of predicting future action and just because we're nosy monkeys. But frankly, what's in Cook's heart doesn't matter. Actions do. And to date, in my view, he's done pretty much exactly the right thing on this issue all along.
Maybe he's defending customer privacy because he believes the Lizard People have religious objections to invading until all humans have Freedom of Math. It doesn't simply matter.
That hasn't happened with other devices or earlier iPhones that aren't as secure.
To be fair - the only reason he's doing it is because it would cause a significant drop in sales for Apple devices. People overseas would immediately stop buying because "The American government is listening", and that's assuming countries like China and Russia wouldn't ban them outright.
This is the big thing American politicians are missing or glossing over in their campaigns to get re-elected: Forcing American companies to compromise their products will result in a significant loss of revenue overseas. Microsoft, Google, et al, have already reported it and foreign governments have already started banning goods/services (due to the Snowden revelations).
