So marketing to law enforcement is unethical? What about all the database vendors that sell to law enforcement -- Oracle, Microsoft, or Postgres? Can't you see the nuances in that?

Law enforcement is the tool designed by the society to maintain the law. That inevitably lead to conflict with civil rights and abuse of power. A healthy democracy needs to protect human rights while giving the law enforcement the tools they need to effectively do their job. Constitution, legal framework, and freedom of expression are essential.
