The question was based on a misunderstanding of how Scrum is "versioned." There's no "Scrum 2.0" or "Scrum 3.0", so the question itself was flawed. The accepted answer addresses this in detail, and I myself added a comment pointing out that this was a problematic way to phrase the underlying question.
In this answer here on meta, Bart correctly points out that the answer was flag-worthy for a number of different reasons. A number of other people agreed, and flagged appropriately.
In response to the flags, the problematic "answer" has since been moved to a comment on the original question. While the post was relevant to the question asked, it was certainly not an acceptable answer as we have defined them within the PMSE community. From my personal point of view, the community addressed the issue appropriately through flags, and the necessary actions were taken.
