Anyway, on the topic, none of the reasons presented in the article seem compelling. Government regulation should step in when consumers have no choice but to use something that has achieved a monopoly, and the payment networks mentioned do make a more compelling case.

It seems inappropriate for regulation to step in when something happens to be popular but there are equal or better alternatives easily available, and changing to a different search engine is about the easiest change a person could make in their life.

In the case of mitigating any bad behavior by Google, there's a very easy alternative solution for the problem, which is to convince people to use other search engines. I haven't used Google as mine for over 15 years and I don't believe I've suffered at all for it. I've found DuckDuckGo to perfectly suit my needs. Google run as a public utility could potentially hurt all the other search engines that many would consider to be superior solutions already.
