Discussing technology, asking "Why", raising the collective "IQ" is an important part of this forum. Advocate your position with facts & figures, or personal experience. Feel free to respond when someone asks you to clarify, no fingers are being pointed. It is your right to believe what you want to believe. Draw your own conclusions.
If data cannot be shared due to classification as company secrets or proprietary etc, say so and leave it at that. Again, nobody is pointing fingers. BUT, be aware that appropriate importance cannot be given to statements using data that is not openly available for analysis. Trust is a good thing, but that is a personal choice. It is not a defensible position by itself.
