This used to be the case when Apple was in dire straits and MS abused their monopoly position to gain 95% of browsers market share. Grim days.
But those days are thankfully long done and there are plenty of people who are completely Microsoft-free.
The one thing people are using one way or another is Linux, because it's now in just about everything. Even those in the Apple ecosystem, with an iPhone and Mac computers, very probably have a Linux router and Linux TV at home.
The number of devices in the world running one version of Linux or another outnumber Windows devices by something like 10 to 1. Maybe more.
Microsoft is a despicable company producing turds since forever. I hate them and the crap they produce with a passion since the DOS days.
As the saying goes: the day Microsoft shall produce something that doesn't suck is the day they'll start selling vacuum cleaners.
