There are probably thousands of game developers, filmmakers, mobile app creators, artists, etc... who would disagree with you there.
Marketing and promotion is sadly necessary to rise above the noise. Kickstarter is basically a way to do a pre-sale which looks like it's going to work out well for all those involved.
Not to mention that it's a pretty big luxury to be able to afford working on something great and revolutionary for the love of it with no remuneration.
This is not a trivial project and it's clear the market disagrees with you.
Kickstarter does not provide enough difference between bad and good choices. You get a t-shirt or nothing. It's an option that nobody would buy in an open market.
This is not necessarily bad. Or good. It's ok. But it is not a market that is in any way fair with respect to capital. And capital does not mean Big Money! Capital means ordinary Joe giving away cash they saved for worse days based on the emotional appeal of something, instead of any rational assessment of its worth.
Moreover, there's a secondary issue with the confusion of market norms and social norms. Ostensibly, this project spawned from a passion for programming. Now, however, that passion is unclear, because it seems to be about money, given the quasi-ultimatum for python support.
