For most people, the funding mechanisms on the Internet pretty much all carry an expectation that they're to support ongoing work that will be used to either explicitly deliver a product, as with Kickstarter, or is to fund an artist's/coder's/etc. ongoing work. Not many people are making donations based on past effort.

I sold a (non-open source) shareware product way back when. Money definitely provided the incentive to put more work into it than I otherwise would have. On the other hand, it made me treat it as a business, albeit a part-time one.
