The pint of complaining to yourself about the price of your fave drink? Not much.
Of complaining here about the price of some silly ship lights on the official forum? To get Frontiers attention as to why you are dissatisfied with their decision. That's how you get noticed, If you are unhappy with mechanics or pricing isn't it? Just not buying it doesn't tell them much, maybe people didn't like the color, maybe people didn't see it, maybe the description was unclear, maybe it destroys users feng shui to hang lights like that. Who knows! But if lots of people say "its too expensive" and then sales are low a lightbulb goes off.
Seriously watching sales decline without any indication as to why is a challenging thing. You have to spend time money to research why and might never come up with a conclusive answer. Lots of people complaining about a specific thing, be it a lack of a feature, price, or just the color, makes life soo much easier. Basically voting with your wallet works a whole lot better if you let the company know why first.
Something tells me that if sales decline they'll figure it out.
