And the people working on national defense have nothing to do with the people working on environmental protection. But, to the extent that you spend money on one rather than the other, it is a reflection of priorities for budgetary resources.
I have no idea how many people at Apple are working on these silly emoji, but it is a reflection of Apple’s priorities that this stuff can get done but they can’t provide a simple sensible update to their highly popular workhorse MBA laptop. Or, they can’t significantly improve tablet productivity by enabling mouse support for iPad (which has been available for years via jailbreak, and does require software resources to develop).
As I have said before, Apple clearly believes that these emoji are popular, and they can maximize profits by creating them rather than focusing on releasing timely updates to the MBA/Mac Mini, or making the iPad much more productive by enabling mouse support. If you look at their revenue share, the iPhone is clearly the dominate product, so Apple is pursuing profit maximizing priorities. That’s fine...it’s a business. But, don’t be surprised that Mac and iPad customers get frustrated when they can’t get updates to the devices they use everyday for school or work, but they can get stupid animated emoji that make silly faces.
