Issue bankruptcy is real. Speaking from personal experience, at some point maintaining OSS is incompatible with living in the real world. The work is free and often thankless (but not always). The problems are complex and compete with real world responsibilities, like work, family, rest. People get pissy and regularly want to argue with you or read the docs for them. It also carries enormous responsibility if your OSS is popular.

I am anticipating a huge collapse in the OSS ecosystem as the people who drive them say "fuck it" and walk away for more important things.
