A lot of people get the idea wrong when it comes to Kickstarter. They sell you on the idea that this is an investment in an "indie" production, or a way to make sure something you love gets made "right".
It's preordering a product that often hasn't even been started yet, outside of enough concept art to sell the idea.
The difference is, when an "auteur" dev delays a Publisher-funded game, they are delaying the Publisher being compensated for the time and budget being used. When we hear people like Billy Kotick complaining about it, we imagine a corporate pig who just wants his money.
In Kickstarter, the dev is now the Publisher. Except, and this is important, he's already been compensated. With a lot of these projects, the majority of people who'd buy it at launch have already backed the project. He's been paid for the project, in essence, and gotten the majority of the return on investment he can expect. At this point (unless the FTC creates more stringent guidelines), the only real reason the dev has to finish the project is community good will, likely to ensure the next project gets funded higher than the current one.
All of that said; yes, I know there are Kickstarter projects and creators who do work hard. Devs who do deliver on their rewards and projects, and do so with skill and speed. There's also ones who keep in contact with the backers to let them know of changes in the schedule and keep them updated about the progress. This is wholly in response to the basic question posed in the comic: "what's the difference".
