It is also a venting place
Actually, it's not. Read the terms of use you agreed to.
where Apple controls everything as they wish without having to comment to the forum. It's a win, win situation for Apple and a great help at times for many people but, as there is never an official response to the forum
All of this is explicitly clear in the terms of use. You agreed to that, but you still signed up. I wonder if the real reason Apple don't reply on the forum is because the quality of contribution is of such a poor level that it would be impossible to. And they have rules, as they must, because a:they're paying for it and b: they could find themselves in court for things said on the forum by others if they didn't. I'm not sure why this is even worth commenting on. That's pretty much standard all over the internet. Apple do provide support systems. Like other manufacturers, after a free period you can pay for them.
Apple are good at design in a lot of regards but rarely answerable except to market dictates
And this differs from, say, Ford or BMW or Boeing, how?
There are some seriously sharp minds on the forum who put a lot of effort into resolving problems and making great suggestions but Apple get all this for free.
The people who contribute do so for our their reasons. In my case, the crossword got too easy. But if you see posting on the forum as contributing to to Apple for free, then don't. That is the simple choice you always have. Further up the thread you mentioned that Android and PCs are "far more flexible". You know that you don't have to buy Apple, right? And if that's what's important to you, this "flexibility", then that should inform your purchasing decisions.
Any time there is a change to the interface there are complaints. (Some are astonishingly virulent. I saw one guy demand on here that an Apple employee should not only be fired but banned from ever working in any form of design anywhere ever again. This crime against humanity? The iTunes icon.) But you know, it's not that big a change, is it?
