Some people would argue that "I" and "What do you care?!" is an example of inward focus, not looking outward towards the user.

Such people would say that ethical and good development should improve the overall human condition and that it should help people somehow. Some others would say at least by doing so it should increase profits for the company than being inward focused.

I think the article is saying that it is irrational not to be developing for Android - even if a developer doesn't like it, they should be making more money...
