Yes, that whole "go big or go home" model only ever made sense for highly-scalable, user facing services. Open source development and support is in many ways the polar opposite of that. Even many B2B services don't really make sense as something where "take lots of outside investment" is the focus. And if you do need some sort of one-time big push to develop something, that's what Kickstarter and other crowdfunding models can support most directly.
