If you want to go that route, money is immoral because it doesn't exist unless people are threatened by force to use it.
When you need to pay the king's taxes with the king's money as otherwise the king's men will beat you up, which is why you'll give the king's soldiers food in exchange for the king's money.
> companies often ensure reviewers
LOL! Of course they do! Companies pick reviewers who give good reviews, and spurn those who are critical. You every wonder why most game reviewers are so fawning?
Consumer Reports knows this, which is why they buy their products on the market, which is why they can't have reviews with the product first comes out.
Which is why when a product is first released you'll rarely find honest negative reviews.
Who rates the reviewers? Are they shilling for the manufacturer? Are they the marketing arm of the manufacturer? How do you know?
