In the world of exclusively human written software the existence of the artefact itself (code, documentation) served as the proof that there’s someone with half a brain behind it. Now that’s not the case anymore.
The conclusion stays though - it’s OSS, authors/maintainers have no obligation to anyone to do anything. Like it, use it, don’t like it, don’t use it.
As for me, I’ve found that the community and activity proxies are still good.
