Why users would upgrade? Windows 11 brings absolutely nothing on the table and on top of that has weird hardware requirements.
It also removes a leg from the table, the one labelled 'usability'.
Attaching a 3rd-party leg to fill the gap helps (https://github.com/valinet/ExplorerPatcher), but it's not an ideal solution
(Still, it's not as bad as Win8 and the big attempt to push a locked-down dumbed-down touch-centric monopolistic-app-store-based replacement to 'real Windows')
My assumed eventual upgrade will only come because Microsoft assures me that they will stop supporting security updates for Windows 10.
The concept of upgrade is appealing in itself, and since the technical details are not understood (or worse, not relevant) to standard users, from their perspective, upgrading is a net win.
