Apple's yield is a little over 2%. That's not a high dividend rate. While it's true that a lack of dividends in a mature company can cause some shareholder dissatisfaction, dividends tend to not pay for themselves in increased market capitalization.

There are companies that use large (10% or more) dividend yields to inflate their share price, which lets them dilute their stock at better valuations. Small shipping companies do this. It's a strategy that's long ceased to be possible by the time a company's valued at a billion USD, let alone over half a trillion.
