By stating that Google is not required to provide the code as offered but only on written request you are very much going by the letter of the document and not by the reality of the situation, which is that by doing that you'd be putting up an unnecessary barrier.

So even if you are 100% on the ball in this thread you have still managed to score an own goal. When people use words like 'required' they don't mean this in the legal narrowest possible interpretation of the words, they mean as in morally obligated. You can then put on your IP lawyer hat and show how good you are at splitting hairs but consider that you are not just speaking for yourself here but for google as a whole by invoking them and appealing to authority in the way you do.
