In reply to Knut Sparhell.

I would agree. None of it is because some are ignorant. The rationale is flawed and the logic doesn't work.

As long as WordPress developers need help with their documentation and refuse to allow people options given nobody, even the developers, knows what all is going on, then there are going to be heated debates. And since so many people didn't realize there was going to be such an impact on so many sites, I would venture into the area of believing that the cause for such "discord" (mentioned elsewhere) is due more to stubbornness than anything else. And that stubbornness is born of arrogance.

As long as there can be such significant issues, people should be allowed to back their sites up before updating. The lack of concern for loss of data is reckless and too dismissive of those who are running websites with this platform as being too stupid to be able to handle such technical things.
