That was an interesting read, thanks, and yes, a few of these are coming to a head. Don't hold your breath on an early conclusion.

There are so many aspects of Google's business growth that brought it to this position. In part, its grip on search and and Android means consumers are a captive audience using Google's services. It's been very astute in getting itself to this position, resulting in growth and size of revenues beyond that of any other search service.
Once that has been tackled, Google's individual services ought to be opened up to market forces, without those forces being penalised by Google over its own services.

I wonder if the antitrust regulators really know what they need to do to open this up, and to look beyond fines.

Fines are cash in pocket. Dealing with proper legislation is work.

There's always a next lawsuit when you deal in such large amounts of money. For example: I'd expect video content creators on platforms other than Youtube to soon be wondering why Google only ranks Youtube videos in their special SERP features.

There is much work to do, and much money to do it with.
