George R.R. Martin pretty famously uses WordStar on DOS. I can't imagine it'd be some win for consumers (either Martin personally, or downstream enjoyers of his books) if he had to be on the latest internet-connected, ad-infested, notification-riddled copy of Windows just so that his OS and Office Suite could repeatedly check to make sure he still has an active subscription and a valid "digital entitlement."
I still use Office 2010. (Though it gets increasingly difficult to activate it, and it last received security updates in 2020.) In 2010 I was using x86_64 (an Athlon 64 X2), and today I'm using x86_64. Why should I upgrade? It happens to still run on Windows 11, but I'd gladly stuff it in a VM to continue using it. (I do use Office <current 365 build> for work, so I can pretty confidently say there is nothing worth paying for in there. The only feature even remotely interesting is PowerQuery for Excel, which is available as an add-in for Office 2010.)
