It's aimed at the U.S. Government. There's been an absolutely massive shift to get to Windows 10, updating systems as old as Windows 2000 to get there. MS advertised Windows 10 as their final OS, eventually backtracking and releasing Windows 11 and will continue to make iterative releases in the future. But for a moment The Government believed it and thought it was a great time to bite the bullet and go all in. Now that most major systems are upgraded to W10, it's doubtful from my perspective that U.S.G. will be able to support or migrate to W11 or even W12, meaning they will most likely pay a lot of money over many many years to keep MS providing security updates for the W10 platform.
