I very much doubt any "ethics committee" or the hiring of "representative minorities" will make any meaningful difference - were it to do so, shareholders would howl and all such interference with corporate profits would cease instantly.

While thoughtful people are right to be concerned at the degree to which the social media/Internet companies control people's minds and behaviors, the harsh reality is that ordinary people simply don't care. They like being told what to do as they stroke their shiny toys. They can't imagine the world being any different from how it is and they can't imagine any downsides. This is why ordinary people rush to pay to install Orwell boxes (hello, Alexa!) in their homes, thus proving the author mistaken when he imagined such things as having to be imposed by dictatorial regimes.

Ordinary people, in short, are the problem. They are the reason the tech companies have been so very successful.
