We know what happens to unhealthy projects over a long enough time period, more maintainers leave, contributions eventually fall, and if we’re lucky users leave it. When we aren’t so lucky adoption continues and years later we’re plagued with security and stability issues in widely adopt software that can’t be effectively maintained.The number of users a project has is a poor indicator of the health of the project, often it is the most used software that suffers the biggest contribution crisis.
