Yes, but look how much of the software economy's infrastructure* depends on underfunded products. OpenSSH, GnuPG and OpenSSL are just 3 projects which are installed on pretty much every Linux server on the internet, including the servers of billion-dollar-businesses. It got a lot better in recent years, but still: Quite a few economically viable software companies just depend on free labor for mission-critical software product which take a lot of resources to become solid.
