Things you might need to know about open source:

• Open source maintainers owe you nothing. We do this because we want to, not because users are entitled to our time.
• Entitlement is rife in open source. Entitlement is one of the fastest ways to burn maintainers out and make projects worse.
• Open source economics matter (and aren't just about money). If you want sustainable projects, you need to value maintainer time.
• The open source contributor funnel is how you grow sustainable community.
• Stop mentoring first-time contributors. Contributors need documentation, automation and scalable systems, not maintainer hand-holding.
• Robot pedantry, human empathy: automate repetitive correctness checks and keep humans for judgment.
