The problem with that is they risk becoming someones "go to guy". There are plenty of people in this world that are simply high maintenance, and if the word got out, the poor BRP guy would be spending all waking hours just babysitting certain people, or risk getting a "bad mouthing" by the same.
The other problem to go long the same lines is that if the BRP rep offers any advice, in some folks eyes, that would remove all sense of personal responsibility. Take the Spyderpops block off plate... If they came out and said that was "OK" to do, then some people would demand they foot the bill to make it happen, and others would probably block every vent hole up, and when their machine melted, they would find the original BRP statement, and file a lawsuit.
I fully understand their hesitation to respond on these public forums.
