Steam should stand for quality videogames, not skininggamersalive scams.
As long as it sells, it goes.
Per your logic, Amazon (and other online stores) should battle negative reviews on pathetic comics. As Amazon aims to sell.
Well sorry, Amazon won't do it. If you're selling garbage (that is a treasure to someone), people have every right to know what they're paying for up front.
No. Amazon aim to sell. This does not mean that Amazon has the same access to means as Steam.
Amazon deal in material and immaterial goods. Steam mostly in immaterial goods. Amazon was also bound to sustain a return/refunding policy for legal reasons from the start.
Steam could do without a refunding policy and introduced its to spur sales: the short time is not enough to tell of a product, it is long enough to benchmark products. Therefore, as not every player has that a smashing PC, it allows players to see if the product could run on theirs without being hammered.
The cost of the refunding policy is low. It does not involve many costs.
On the other hand, AMazon return policy is of higher cost. It includes shipping, recycling, stocking etc
It is all a benefit for Amazon not to dilute the meaning of negative reviews as it curbs down the costs linked to refunding/returning.
This type of constraint (and others) do not exist for Steam.
The pattern in consumption also differs: people might not collect vacuum cleaners. They look for one and when one is hit by negative reviews, they look for another. They behave the same way as customers who benchmark a video product for one hour and half to see if it runs.
Players might collect products in genres: having one is not enough for them and they will stack. Once customers have bought a vacuum cleaner, others are excluded. It does not work that way for vid products. Once you have bought one, you will buy another, including clones.
Diluting negative reviews come at fewer costs for steam.
