You do realize that for even a slightly noticeable impact on sales it would take so many more people than what anyone here could even imagine organizing that that effort is likely even less realistic and useful than submitting feedback
You do realize that even submitting feedback doesn't give Apple any incentive to fix the bugs. Apple has no reason to fix any bugs, if people keep buying their buggy products. You could file, 5 billion bug reports, but if their sales are doing great and still growing, no one at Apple will lift a finger. Welcome to capitalism!
