Firstly, companies spend a pretty penny to associate their brand with vague positive platitudes. In the first place being associated with something negative even if their populace doesn't understand the technicalities can be worth more than 1% of your business.

Second tech savvy users influence others.

Thirdly supposing you publish sufficient tech specs as to enable the kernel to support your hardware I'm guessing linux users actually require less not more tech support.

Windows users repeatedly trash their own machines with malware and pick up the phone to call their oem. Linux users google the error message and open a bug on the project that actually doesn't work's site.

I'm not even sure where your hostile attitude comes from. Lenovo just dropped the ball.

Magic windows bios raid modes have existed for the 13 years I've been using linux and I have never seen one that didn't include a switch in the bios to disable it.

What you are incorrectly framing as lenovo righteously dumping entitled linux fanboys is in fact just Lenovo not knowing how to design a computer which given repeated mistakes in recent years is hardly shocking.
