On the flip side... Does it really matter?
I just checked and I could get a $100 off my ThinkPad of choice by selecting “no OS”. To me that’s more than sufficient.
I’ll setup my Linux the way I want it anyway, and you better believe that’s going to be from scratch.
Edit: from scratch with a vanilla installer. Nothing zealous or crazy.
Edit 2: I also found out my (Lenovo) work-computer is seamlessly receiving BIOS- and other FW-updates seamlessly via fwupdmgr in Linux. I have no reason ever to boot Windows on that thing.
All in all, happy Linux-using Lenovo-customer checking in.
