This is exactly why it's important to bust them up: all those other products are effectively "dumping" on whatever sector they compete in. This even discourages time-investment (to develop) and learning-to-use investment (for users) for free alternatives, not just commercial ones.
All of their products helped the sector they are in. They didn't "dump" into it. Google continually improved areas where other companies previously refused to, even if they were charging for their services. 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…
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.
