I'd quibble with "Tim Cook's money-is-everything reign" because that's an interpretation you put on what you experience, not necessarily what it really is, but I think whatever-it-is is exactly what Apple pay him to do.
I also think you have to remember that Apple began in a rather different economic environment than is prevalent today. Then, selling out of a garage, and establishing themselves in the market, the marketplace was highly volatile, and Apple had a narrow product profile which was easy to market and support. Today, after Milton Friedman began the age of 'stockholders are to be pleased at all costs' in 1975, which is the prevailing economic theory even today, the CEO of just about any publicly held company has to focus (predominantly) on that. He has necessarily diversified the product range to protect the company's future, and moved to protect Apple's revenue streams. That's his job.
Whether a reputation for 'CUSTOMER AND PRODUCT' has ben sacrificed, and if so, how, is somewhat a matter of personal opinion. Having lived the fiasco of 128K RAM in the first Mac, the inflated cost of the first PowerBooks, the egregious mess that was the PowerBook 190 and 5300 product ranges, the confused and complicated, virutally impossible to navigate desktop systems products of the 90s, and the reliability of the G3 iBooks and G4 PowerBooks, the overheat issues with the G5 Desktops and first generation Intel MacBook Pros... Apple's history isn't quite a nice as you suggest.
Personally, I don't much care for him, but he has proved to be extremely good at the job he is paid to do. Sadly you (and I) are not his employers and don't dictate his responsibilities.
