You can't break up Google without breaking Google and I think that's what they were going for in the first place.
Eh, not really, but close.
For example Chrome was greenlit because “if successful” it gave Google a web browser they controlled and they could use it to make sure nobody ever made it impossible for Google’s ad system to work on the web. It wasdefensive, built in an era where Google’s fear was Microsoft’s IE becoming dominant and ad blocking Google into non-existence.
Chrome doesn’t make any money because it is very hard for a web browser to make money. Other companies already offered free web browsers of reasonable quality, and web browsers are big and complex, funding development of a world class web browser is expensive, far more so then they could earn if they had to rely on customers paying for it.
So Chrome’s existence independent of Google’s ad revenue propping it up is a tough sell. That wasnt’ designed to make it impossible to break up Google, i.e. it wasnt’ a strategy to design Chrome as a self destructing chunk of economic value that people will be upset to see fizzle out of existence because the big old mean government curb stomped Google. That is a pure side effect.
It isn’t dramatically different form Apple and Safari. Safari exists because IE for the Mac wasn’t very good, and having a major platform with a crap web browser isn’t a tenable prospect. Even in the early 2000s. You can make a more compelling argument that Safari is part of Apple’s core product not a “bundling for business purposes”, but it is still an expensive bit of software that couldn’t justify it’s own expense with direct revenue if it had to sell itself as an independent product.
Most of Google’s products make very little money, a result of Google spending decades trying to figure out something that could be as profitable as the ad business while internally being flooded with ad revenue so not being forced to kill off things that didn’t turn an actual profit. So it ends up with youtube (likely very profitable on it's own), maps (only profitable if you monetize ads, but very profitable if you do), and multiple chat and voice clients every few years and so on that just don’t make money. They probably could if you had to run them as a standalone business (see Zoom, and Slack, Google could have had that level of success, if they had decent marketing and aimed the products right). Plus things like the Nest line of products that were profitable before Google bought them. Or smartphone hardware which a few other companies manage to do at a profit (and to be fair most of them outsource the expensive R&D to Google, who has nowhere to outsource that too!).
