Fundraiser posts like this are not great for HN. That a cause wants money isn't intellectually interesting. If the project is new and significant, I guess it's ok. But it would be better to link to the most substantive page about the project, and mention the fundraiser in the thread.
Crowdfunding is a great thing, so I'm not sure exactly where to draw the line on this. What I'm sure of, though, is that posts entitled "Just 12 hours remaining to hit stretch goals" shouldn't be here. This post wasn't like that, but others have been.
I'm not casting doubt on the merit of any particular fundraiser, and especially not this one.
