There are 387 posts in the thread you refer to, not 5000. Since that thread was finally locked last fall, there have been no new posts here about the multiple different symptoms and underlying problems that all got mixed up in it, or about how Apple dealt with any of them. You can wait for people who contributed to that thread to tell you what the outcome was for them. But like it or not, only Apple is going to decide what it's willing to do about your problem.
