Ask HN: Examples of projects that died with their core developer
2 by vimax | 2 comments on Hacker News.
I was thinking about long lived projects and the "bus factor", and it got me thinking about projects that died with a core developer. I can think of projects that have outlived their core developer, but I don't know of any projects that ended because a developer died. Linux is certainly large enough to outlive Linus. TempleOS continues to live. Dwarf fortress might not be maintainable by others if the worst were to happen, but there is a very dedicated community. Are there any examples of the bus factor actually ending a project?
