Win11's telemetry load is significantly higher than already outrageous win10's to the point I feel it is a legitimate security risk.

Things like passing off your wifi passwords in plaintext to MS servers is really only the tip of the iceberg.

When w10 goes End of Life, I'll be buying 3rd party microcode patching from 0patch.

Screw w11 with every fiber of my being.

It's totally fine to upgrade from Windows 10 to 11, it's basically the same thing. Overall it's better in some regards (like better HDR support, direct storage is coming and so on) and a bit worse in others (I do hate the new right click menu). No ads though and barely any difference to Windows 10 as far as I noticed in over a year of using it.

Windows 10 already had all that stuff, telemetry, a link to Candy Crush in the start menu, it's the same shit. Windows 11 didn't get worse in that regard at all.

So just do a fresh installation of Windows 11 (don't upgrade Windows versions, it's a mess in the background) and have fun.
