The vocal minority. How many times do you go to hundreds of websites after a purchase to spread around how much you're pleased with what you just bought? No, just the complaints are spread around. That makes any issue appear greatly inflated.
Don't get your hopes up- this will not sink Apple or the iPhone. The press is the only one perpetuating the problem, for their own gain, and that's keeping some people from purchasing until an acceptable fix is produced. Some.
