⚖ Ethics

It is the duty of software engineers to build software in an ethical way. In short:

  • computer systems should serve their users before their makers
  • software should empower users, not restrict them
  • users should decide how data is used before engineers or businesspeople

Whether it means embracing software freedom or another ideology, or going by gut feeling, we must proceed as best we can.
