If Google comes up with the plans, it's better than some antagonist.
Mail. Internet browsers? Does it really need to be stated? Open source. Kubernetes. Open source. Tensor architecture. Freely released.
I don't see the argument for breaking Google up other than people are holding some vendetta against Google for being successful AND a pretty good citizen in the overall landscape so to speak.
If anyone needs to be broken up it's Microsoft. Microsoft actively harms every other competitor by bundling all their services together to the point where businesses won't even look at other software (teams? Azure is basically sold on nepotism).
Their cloud generates a couple of billions in profit each year.
Besides that, I don't think giving away anything for free justifies any activity. If we're trying to compare to Microsoft, remember that Internet Explorer was free, and modern day Microsoft literally owns Github.
Google is not anti-competitive. At no point am I forced or even "guided" into doing business with Google, at any stage, in any department. There are 8 billion other ad-networks out there, and there are plenty of mail providers to choose from, and plenty of search providers to choose from, and plenty of cloud providers to choose from. If you're on gmail (even business), or Google Cloud, or Adsense, there really isn't much stopping you from switching to something else. There's no real lock-in.
You cannot say the same with Microsoft. A lot of businesses are so dependent on MS's offerings they might as well just be glorified subsidiaries. You don't really have an Excel drop in, or an AD drop in, or a messaging app drop in that comes with all the other services. Google doesn't hand out Cloud credits with the express purpose of roping more of your business infrastructure under one company.
Internet Explorer was not free. You needed Windows. And if you had Windows you HAD IE, regardless of whether you wanted it or not, or even tried to remove it.
While you're welcome to this opinion you might want to address the fact that Google has recently lost THREE separate trials, each of which individually and separately produced a verdict that they are, in fact, in violation of laws against unfair competition.
