Because Tim Cook is very activist, as long as he does not hurt the sensitivities of the leaders in the markets. That is what has happened to Apple now in its latest launch, and that is that the red iPhone 7, which we assume has been launched for a good cause, does not seem so much in China. The Asian country carries out a campaign of repression in the media to omit content related to AIDS (out of sight, out of mind) to which Apple herself has submitted, especially considering that supposedly these red products are launched to help against this disease.
Except in China, there the iPhone in red seems to have nothing to do with the fight against AIDS, but one more color of the many that Apple has in its range. We do not know if Apple will really allocate the funds corresponding to the sale of the iPhone 7 in China, but on Apple's website in China there is not a hint of advertising that should be done. Curious at least that such an activist company in some areas, submits to a power of this kind.
And it is that from my humble point of view, it would have been more honorable not to launch a product in a country where it is not possible to freely express what is the cause of its launch. The reasons alleged by the Chinese Government For these types of measures they are merely religious and political, since knowledge is power, and the more people know about HIV, the more they will know how to prevent its effects, however, in the Asian giant they decide to turn a deaf ear.
Ultimately, These are the real reasons why Apple does not advertise its (PRODUCT) RED in ChinaWho are we to question it?
