I raised a flag "Not an answer" on a answer to nine year old question.
The question is "How can I determine the current firmware version number?"
And the answer I flagged as a "Not an answer" was answering that the Raspberry Pi OS Rasbian has changed name to "Rasberry Pi OS".
In my understanding "Not an answer" should be used "flags should not be used to indicate technical inaccuracies, or an altogether wrong answer".
And to answer "The OS has changed the name" is not an answer to "How do I check what firmware version I do have".
