I'm not sure why people keep saying opinions on a forum don't represent a real issue.
It reminds me of the BMW forum I frequent. HPFP (High Pressure Fuel Pump) units kept failing left and right from 2007-current (although much lower rate) and everyone on the forums kept claiming that this does not represent the majority of cars on the road.
BMW finally acknowledged the issue after being brought a lawsuit in 2010.
Because this forum is mostly populated by people who scrutinize every nook and cranny of their device as soon as they get it and have a tendency to overreact to every tiny issue. The average consumer doesn't even notice these kinds of things. I know dozens of people like that who have iPhones and iPads and when I mention any of these kinds of issues, they are like: Huh? What are you talking about?
People here freak out over one stuck pixel or take their device into a dark room with a black image on their screen and pore over every inch to see if there's any light bleed etc... The average person doesn't do any of that.
People on these forums read about all of these supposed issues and then put their device under a microscope as soon as they get it looking for those same issues. I do it myself.
The other thing with Internet forums in general is that the people who post the most are people that are not happy or have an axe to grind etc... I've spent many many years on forums of one kind or another and I can tell you that a forum is definitely not representative of the population in general.
Just to use your BMW forum example. Let's say there are 10,000 people driving that same model around and some people are having a certain problem. Those people will go looking for other people having the same issue and they will all get together on a forum and make a lot of negative noise about it. You come along and see this and think that it's a huge issue affecting most owners when it may just be a small percentage of people affected. The vast majority of the 9,500 people who are having no problem will not join in and talk about how great the car is. A few will, and they will get shouted down for daring to insinuate that the complainers problems are not real. happens here all the time.
I think it's good to keep some balanced perspective. Sure, some people are having real issues or problems, but that doesn't mean that there is some huge problem. "How can Apple release such a piece of junk" "This is criminal" "This never would have happened if Steve were alive" and so on.
