I think it's being pointed out that people who share your experience generally have a pretty extreme lack of awareness which everyone else can easily notice.
An announcement about a new iPhone or iOS feature will inevitably have Android supporters bashing on literally every single person that owns an iPhone, making childish character judgments about strangers.
If an announcement about Android happens though, you do not get a bunch of iPhone users looking to criticize the Android fans at all. We just don't care to go through such a pointless exercise that is willfully engaging in extremely poor logic. It's raw and unfiltered stupidity to generalize about any huge group of consumers solely based on a product they use. Use whatever you like.
