I agree with your point of view - many people pay the minimum $20-30 for bare digital download, but the real drive for Kickstarter campaigns are all those people who shell out/maximize their credit cards $50-10,000…. I myself paid $55 for Wasteland and $70 for Eternity and I usually buy games from gog.com or GOTY versions when they are below $50… I view Kickstarter as a platform that can make creators and mine dreams come true, but apparently some people started to view it as "easy money" - a place where people just throw money at you - i.e. Old School RPG/ SHAKER Project and other less important projects…
But on the other hand Brian Fargo has a point as well - if his ideas for the sequel are not going to be accepted by the community than it is better for everyone involved not to make the game at all…
