The reason for this is because switching from Windows to Linux is a lot bigger change, requiring a fair amount of technical know-how, and even knowing that Linux exists in the first place. Swapping browsers is easy in the technical sense, it's breaking the habit that's the hard part, but if they piss people off enough all it takes is uninstalling it in order to break the habit, not a drastic paradigm shift. I'm a long time Chrome user, like over a decade and with the recent "unverified download" nonsense unless you enable their invasive tracking has put me over the edge. I had both the Chrome and Firefox icons pinned to the taskbar and just out of habit kept clicking it, I finally removed it last week
