Comparing Google to Microsoft in the early 2000s is not pointless at all. Back then it was Microsoft who had the monopoly on all technology, they controlled IE, the most used browser in the world, and they controlled the main operating system that people used.

When Google started Chrome they worked with other large companies to work on building web standards, many of the super important technology behind the scenes that make the modern internet work were developed at least partially by Google in collaboration with other major industry interests.

Android also had a huge impact here. These days people accessing the internet on phones is common practice, but once again Google pioneered many of the standards now used to allow build applications that run decently well on phones and can interface with the web.

And those are just two major projects you've likely heard of. Google created a lot of tech that is used behind the scenes:

• Kubernetes was created by Google and they have transfered ownership away from themselves.
• Golang is a wildly popular development language that they developed and open source.
• Related to android, but google is also a major contributor back to the Linux kernel.
• Google is also a major player in online security proactively finding security flaws in critical web services and applications and working with relevant parties to resolve them.
• Google essentially developed http2.
• Google was heavily involved in developing HTML5 (which really was essential for our modern websites)
• Google's open source V8 JavaScript engine is used in node.js (another super popular web development language). I think it still uses V8, but I haven't used nodejs in years.

I'm not saying you shouldn't try to use Google products less, but this case you're ignoring just how much Google helped save us from Microsoft's monopoly. And regardless how much control Google has now, it's far less then the control Microsoft had, and a large part of that is because Google has been more open with their technology and more willing to work to better the entire industry (yes they were likely aware that making the whole tech space better would also help them, but i have a hard time feeling that's malicious)
