A major vulnerability with a sincere response is not that bad. Software is very difficult. What killed my respect for the zoom team was the PR bullshit that they engaged in after it was discovered. Major companies have been known to fuck up and recall their faulty products or offer reasonable solutions (e.g. exploding batteries on the note 7, the intel chip bugs). The reaction shown by zoom was that of a whiny child caught in the act of stealing cookies and denying it all ---"Those are not really cookies you see!" It was so ridiculous it was not even offensive.
