From a health-of-the-system perspective it really should be intolerable that a few large closed-garden platforms control the flow of information. Information monocultures are a threat to everyone, even if one partisan group feels more threatened than the other at any one time.

I happily take the market-efficiency position on most debates, but the risk of Google being anything but neutral is worrying. They appear to have a political bias in their employee base and are under pressure to make judgements about fact v. fiction (might even be an inherent requirement of choosing a sort order for search results) - that is a position somewhat similar to a conventional media organisation.

I support the concept of media being a special case where the risk of an information monoculture outweighs the damage of being inefficient. Laws that basically make it impossible for one media source to control a market are fine. I'd like to see internet search designated as a market where there legally can't be one dominant player, and details get sorted out as best can be done.

Maybe that is already how the market is, I don't know. There are many alternatives not controlled by Google. But something even stronger than antitrust seems appropriate as a matter of law, even if we don't apply it today. I can't see how a platform like Google can be neutral given the ongoing partisan extremes that have developed in American politics and Google's connections to the Democrats.
