I'm often less excited about a solo dev doing "freeway out of the kindness of his heart" and more interested in seeing OSS software gather around a foundation scheme with some corporate sponsors, Blender-style
I don't know much about Blender but if OSS still needs corporate sponsors to stay competitive:
- What's the point? Might as well become a for profit company themselves then.
- Why would any for profit company sponsor FOSS? They will literally not make profit on it.
