I can assure you that a problem that is as widespread as you suggest does indeed cause an overwhelming outpouring of complaints here. I want to say again that the number of complaints about this issue seen here is not very large.
But Apple pays MUCH more attention to the number of individuals reporting issues as a Bug Report on the Product Feedback pages:
https://www.apple.com/feedback/
.. contacting Support for assistance (and potential filing of Formal, Tracked Bug reports),
Support
... and getting their units repaired.
https://www.apple.com/retail/geniusbar/
No heroism is required -- take care of your problem, and you contribute to the overall solution.
-------
When those numbers seem excessive, THEN Apple does the Engineering analysis to find the cause. If the cause is component defects or manufacturing process defects, then a Service Program is initiated.
If you have already paid for a repair covered in a subsequent service program, Apple will reimburse you.
Executive Summary:
This is a User-to-User Support Community. Readers are other users like you. Apple does not participate with technical expertise on these forums, demonstrating that they do not wish to address your problems through this venue.
Posting your conclusions about Product Defects here is extremely unlikely to spur Apple into any sort of action.
