Counterpoint: I write open source software that lots of people use, and I receive approximately 95% thank yous, 4% simple requests for help or features, 1% attacks/hacks/complaints.
The secret (IMHO) is keep it simple, so people know what they're getting and can figure out how to be successful.
70M downloads of my oldest project, Ruby unaccent port: https://github.com/sixarm/sixarm_ruby_unaccent
200K downloads of my newest project, Rust testing macros: https://github.com/sixarm/assertables-rust-crate
Open source authors inspire me every day to create, improve, and share. The point isn't money; the point is helping each other learn, explore, and grow.
