The parent has pegged a round hole with a square question. Hardware support in Linux works well if you build your own machines, or happen to get one with supported hardware. How do you find a system that is fully supported and for which distributions?

It is probably pretty easy to make the sort of argument you are making the style in which you have made it. When you start off with a exclusionary qualification of opinion and then follow up with redefining an indefinite group under your own terms there is little anyone can say to disagree. Since there is no big "L" liberal group which has a definitive stance on any of the topics you've mentioned you can define it however you want and then easily attack the straw man which you've created. I think you've named your straw man "they."
Perhaps if your arguments have real merit, in the future you can elucidate upon them in a way where you are able to define specifically the group which you are attacking and then point out, by specific example, the flaws in their position and/or method.
Maybe I've succumbed to a troll here, but I feel generous in the spirit of the winter holidays and would rather put my effort towards elevating the quality of this type of discussion.
