Did you know the W3C published Ethical Principles for how the web should work?
https://www.w3.org/TR/ethical-web-principles/
I find them so inspiring. And they guide what developers should be doing, too.
“The web should empower an equitable, informed and interconnected society. It has been, and should continue to be, designed to enable communication and knowledge-sharing for everyone… we need to consider the ethical implications of our work when we build web technologies, applications, and sites.”
