On principle I hate the idea of encouraging people to submit reviews for products that they haven't purchased. It's a crime worse than time-bombing generic printer cartridges and makes online reviews basically worthless. I don't give a shit about your moral stand against HP. Give me an honest review of a product you own or don't say anything.
Disagree. You don't have to own a product to write an honest review of it. You don't need to have a Galaxy that caught fire to warn others of what's happening. I'm going to leave a 1-star review because my review is an accurate description of the product even though I haven't owned it. The real problem is people who review products on unrelated issues, like the political positions of the CEO.
It's easy to quibble with this in cases like the Samsung batteries. But exploding batteries aren't the common case: much dumber things are.
