The question, as always, is who watches the watchmen? We saw what happened with broadcast and telecom regulation for phone and radio/tv in the USA. ABC, CBS, and NBC held a virtual monopoly until cable news 60 years later. AT&T/Ma Bell did likewise. It was horrible and arguably retarded innovation and diversity of viewpoints for many years.
It's not. We're so used to being totally unregulated in tech that even minor oversight can be spun as burdensome.
