A recent report by Tidelift analyzed the workload and habits of open source maintainers. The report looked at the survey responses of over 300 maintainers — the people who create and maintain open source software projects.
The report found that maintainers are being asked to take on additional work to meet government and industry standards, even though 60% of maintainers describe themselves as unpaid hobbyists. Thirteen percent describe themselves as professional maintainers who earn most or all of their income from maintaining projects.
