I don't even see how European style mom and pop scale businesses even suffered because of Microsoft. On the contrary, the adoption of Windows is much higher in Europe than it is in the US, understandably so. I doubt there are businesses outside of tech anywhere outside the US based on the MacOS. And because Microsoft took a reaaaally lax attitude towards copyright enforcement, everyone in the old and developing worlds basically pirated Windows, Office, etc to oblivion.

In my books, post the antitrust case against it in 95, Microsoft has been the least monopolistic of the bunch, and a net positive to the rest of the world.
