Yes, great point. it's because it will sell amazing anyway, and therefore any opinions outside of that are ostracized and criticized. I mildly criticized the iPhone XR for having a sub 1080p screen here, and had people up on me for that one too. "It sold well, so you're wrong!". Not a great rebuttal unless I said it wouldn't sell well. I still said it would be good iPhone but I found that disappointing. Some here even noticed the less sharp font to their iPhone 8 Pluses. So yes, specs do translate for some that care or do notice.
McDonald's brought in $37 billion in US revenue, do those sales figures make it great quality food? Nope. In fact it ranked the highest in sales, but lowest in quality of food of the fast food chains. ZERO correlation. While I love my Apple products wholeheartedly, it doesn't make me blind to any potential flaws or areas I'd discuss that things can improve. Especially since we discuss future iPhones.
