The longer answer is that outside of a few niche manufacturers like Framework, System76, or MNT, the trend seems to be away from having a true "personal computer" toward having an iPad-like device that connects to the internet and some sort of app store where you're sold services. It's sad, but I think the era of personal computing is well into its twilight.
> What struck me first is that although I could get that model with Linux preinstalled, in that case I was limited to a most basic model (like 16 GB of (soldered!) RAM). That didn't make a lot of sense, so I swallowed my pride and decided to pay for the Windows - that I'll delete immediately after unboxing, but that was the only option Lenovo offered. For better or worse, I became a proud owner of 21K5000DSC.
Hm, no, that's related to Lenovo's distribution channels and (probably) licensing agreements and has nothing to do with official Linux support. That same model can be bought on other markets with Linux preinstalled without problems and one poster from that thread already confirmed that.
