Funny, iPhone users spend most of their time reading text in Safari, which has always been black on white, yet nobody ever complained. Your whining will fall on suitably deaf ears... Better start shopping elsewhere.
There are mobile sites out there (Ars Technica for example) that have an option for light on dark theme, which makes for easier reading at night. I wish more sites would do that. But for many apps out there, the devs have opted for the same overall bleached look of 7. I'm sorry my whining annoys you. Perhaps next time you should just refrain from reading it.
