Well, I agree that there was much noise, especially around the whatsapp discussion.

However, keeping the discussion in a single confusing and unclear thread does imho not help in reducing that noise.
Instead, having dedicated threads per topic would make it easier for users to find information and answers about specific questions and keep the discussions on-topic.

In the actual case, I really think that the user followed best forum practices. While I can understand that, at that time, the mood was heated-up here, seeing this in retrospect, it should have answered and handled differently.

Personally, I think that closing a thread should be the last resort ("ultima ratio" in Latin). I also very much favor polite answers instead of blunt and rude attacks.

I also do not think that there are bad things done purposely. I just think that this is an example of how a legit and absolutely valid request got handled very badly.
I also don't want to blame anyone. I just put it up here for two reasons: firstly, I'd like to have that thread re-opened to have a central place to discuss this issue.
And, secondly, have the discussion we are having right now in order to sensibilize with respect to the general issue of closing threads or handling potential duplicates.
After all, we are a big community and things that bug some member get discussed and sorted out by communicating with each other.
