You’re completely missing the point to a level that feels dishonest. You’ve already gotten a great reply around why you’re wrong on Microsoft so I’ll keep to Google.
Google started out providing the superior service and didn’t do anything overtly shady. Then the shady shit started, cloud storage was one thing as mentioned, others include doing the Microsoft thing of not following web standards properly, in Googles case with the argument that their way is faster/better etc effectively forcing everyone to code towards their browser (chromium, not just chrome) since it has insane market domination.
Another, and maybe the most egregious because they haven’t been slapped for the other stuff, is the privacy bullshit they’re doing now around cookies which basically kills off the last remnants of competition around ads online.
Google as the default search is just the tip of the shitberg of monopolistic bullshit imo.
