Warren Buffet seems to agree: Berkshire Hathaway built a $18B position in Apple recently. And I'm pretty sure that he would love nothing more than for Apple's stock price to go down in the short run, so that buybacks increase his percentage of the company even more.
I guarantee if iPhone sales plateau every shareholder who dumps their share will be replaced by a new shareholder. Value investors love nothing more than predictable cash generating businesses with low capital requirements.
No tree can grow to heaven and the growth potential for the most profitable business on earth is equally limited. There are investors for zero profit growth "stories" and investors for proven businesses with tremendous moats.
