I see you're expressing an "opinion" too ... :-) ...
However, there are multiple millions who are "not here" getting help, and there are only a very few who are here getting help. The iOS media/news reports do not report the vast and overwhelming majority of the installed user base having problems ... and believe me ... if they were, THAT would be "news". It's not there. There are reports that a few are having problems, as is the case with every major upgrade that has ever been done, since the very first iOS device, the iPhone.
No, it's not a major problem. But, it is a problem for an INDIVIDUAL user, which it's necessary for that one user to fix for himself or herself. These are individual problems and problems that are related to the usage and perhaps corrupted files and maybe corrupted installation process for their particular machine or even a possible hardware failure.
I would tell all users to get a hardware check on their iOS device regularly, just to log the results over a period of time. And you should expecially have a hardware check if you're having problems right now.
Schedule a hardware check here ...
