True, but letting others know of both your positive & negative experiences with a company, product, etc. helps to guide their steps. When a consensus builds we know which ones to rely upon, and which ones to avoid. For any company getting the finger, do whatever it takes to get the thumbs up instead.
"pointing the finger" to blame someone or something is completely different, in my opinion, to giving a negative review on a product that doesn't perform to what it was stated to do.
my build thread has a couple of "failed" reviews.
