Car ownership often doesn't go well for you if your stupid and incompetent. Making linux work on all possible machines with very very finite resources is an impossible task.

In that context keeping people from buying machines that don't work with linux and complaining on the internet is equally impossible.

I don't understand how you believe people are obligated to do better work for free for you.

*Please note I'm not implying you or the author are stupid just users in general. This is why most people ought to buy complete hardware/software packages with support and experts should be able to use google and read docs.
