Things were a little bit different in the late 90s though. Windows had a 97% market share and a massive deal with pretty much every computer maker to only put Windows on their pre-built machines. They had a true monopoly in a way that doesn’t exist today.
They also made IE free and bundled with the OS when every other browser at the time you had to buy. On top of that, they made it so that windows would slow down and malfunction if you uninstalled IE, and made installing any other browser a complicated process.
Today you can freely and easily install pretty much any browser you want. Chrome has the hugely dominant share in the the desktop browser market now, despite Edge being bundled with Windows.
On top of that, Microsoft doesn’t have the massive stranglehold on OS market share that they used to. In the desktop space, MacOS is about 1 in 6 computers with Windows holding 71%, mostly in the enterprise sector.
And this doesn’t even factor in that the majority of web traffic is mobile now, where Windows doesn’t even have a presence anymore.
