Problem wasn’t IE6, it was the fact that Microsoft bound versions of IE to versions of windows. You had IE6 lingering in substantial numbers seven years after it was released due it being the only IE option for Win98. People couldn’t upgrade to IE7 unless they upgraded their machine to WinXp. It’s the same problem with safari and iOS/macOS versions.
