Comments only have two sanctioned purposes: clarification of the on-topic material of a post, and asking for such clarification. Any other use subjects them to removal.
Beyond that, a good moderator will refrain from taking any action at all unless the community shows some interest with their flags.
In this particular case, I see several comments that are either unnecessary, obsolete or just plain noise, and I plan on flagging several of them. In particular, the debate over whether the question is a duplicate or not. The remainder of the comments continue to be too lengthy because certain people would rather get into a debate instead of accepting some facts that were presented in the comments that are not only factual but obvious.
Even then, content like that more properly belongs in an answer and not a comment. I tried posting such an answer, but it wasn't received well and the participants seem more interested in engaging in pedantry than accepting the obvious.
