I would love to see how you feel if your electric company overcharged you for years and owed you $1000 when you found out, and then decided it ain't really worth responding to refund requests.
Don't you think that is a slightly different thing? Just a little?
1. If an electric company overcharges you, they are in error. They have charged you more money than you agreed to pay whether that is per KWH or per month or whatever.
2. An electric company is obligated by law to respond to grievances as they are a utility. They're also heavily regulated by law as to what they can and cannot do.
Now this kickstarter situation:
1. You were only charged exactly what you agreed to pay, with the knowledge that the money would be used to fund a creation process.
2. The creator is under no legal obligation to provide or even respond to refund requests. This does not make anything a scam, it's just how Kickstarter works.
You've talked a lot about what you want kickstarter to be but that isn't what it is. If you want kickstarter to be something it isn't, some dream you have for a crowd-funding website, then go make your own crowd-funding website and make it the way you want it to be. Kickstarter isn't going to change into what you want it to be just because you want it to.
The fact of the matter is that you accepted the kickstarter terms of service, you pledged an amount of money to a project with an uncertain future, and now that the uncertain future has (gasp) been shown to be uncertain you are upset. Accept that you made a bad decision, or be patient and maybe eventually get your game that you paid for.
Or just keep blaming other people for your mistakes I guess. You seem to be very focused on how everyone has wronged you and nobody is doing it right. Is that working for you? At the end of the day, as far as I can tell they have broken no laws nor have they violated any kickstarter rules. The only one responsible for you being parted from your money is you.
