The people in the report (not necessary the original submitter, the "Now I'll go and tell everyone to uninstall Signal! There you have it!" crowd) seemed to be demanding/whining and spammed a bug tracker with random anecdotes and their personal agendas in a rather rude way.
Whereas moxie - again, in my opinion - replied in a very friendly, objective and calm manner and invited these people to discuss the issue further. In the _right place_ for an open debate about design decisions.
