Ethical is nonstandard between people. It isn't so clearcut. Barring the whole 'investors, stockholders, etc. Fiduciary responsobolities' Its less about tech and more about business ethics needing a cleanup via legislation.

There's actually a huge amount of agreement between people on what is moral and immoral.

That fact forms a big part of some mainstream arguments for moral realism.

I think we need both internal activism and external regulation

Exactly. How can you have tech when these unethical people aren't stoning people for wearing mixed fabrics?

This was the point of the ethics class in my computer science curriculum.
