The usual impetus is that the official status pages habitually under report and sharing the status page showing the best information gives a basis to form a place to have discussion about where/how/why it was down. Unfortunately, many seem to take the other interpretation instead and said discussion often ends up being low quality in a self fulfilling loop of reasons.

The second note probably deserves to be a separate comment.

This is a good take. You are right, they rarely do report actual status.

And yes, it probably should have been :)
