Google are smart enough to maintain a duopoly (iOS, Office/365, Safari) Whereas Microsoft tried to kill all competitors (and all too often succeeded). That’s a huge difference.

So far. ¯\_(ツ)_/¯

Though Android's marketshare today is extremely similar to Windows compared to macOS early in the period for which Microsoft is criticized. Similarly, Safari and Firefox combined have low enough marketshare (currently estimated around 21%) versus Chrome estimated 65% (and growing) to make real, very concerned comparisons to the early parts of the IE6 era, if not its peak (yet).

The difference is that it is still early and Google hasn't killed their competitors yet. I can't tell you whether or not they are "trying" to, just that I agree with the above poster that Google has the potential to be worse, and possibly history repeating itself on some of the exact same product lines.
