Lets say that CS is a chair and Valve's the engineer.

User thinks the chair is fine, but some armrests and cushions would make it even more enjoyable.

Valve adds one armrest and a piece of cardboard for a cushion. Because thats what the user asked for.

Valve also adds a 5th leg to the chair because it looks nice. However, the 5th leg is 10 centimetres longer than the other 4.

Users complain that the chair is now not fun to sit on, and that they didn't want the 5th leg to begin with.

Valve shortens the leg for 2 cm.

Users keep complaining about the 5th leg and demand that it's removed. They also want the other armrest.

Valve colors the leg pink and makes 2 of the other 4 legs longer. They hint about the other armrest making its way.

Community states that the chair was just fine before the changes and it should be reverted to what it used to be.

Valve adds some music to the chair. And paints it green and blue. And makes a hole in it.

Users are full of Valves ♥♥♥♥, but because they've used their chairs for 23 years, they don't want to change.

Valve adds a balloon to the chair.
