I mean first off, yes most people using Linux have no problem with helping people out, my guess is linux users are probably 100x more active on support platforms than anyone else. (if not more)
But also, who on earth has Microsoft customer service? Big businesses sure, but do you think most Windows users get customer support, big tech companies stopped connecting you to a human being like ten years ago. Everyone just googles when something breaks no matter the OS. I'm just so tired of the meme that there is any meaningful difference at this point. I've been using stock Ubuntu Desktop for 12(?) years, out of the box, no weird tinkering.
Do you know how often friends and family call me because something broke on their Windows machine and I'm the "tech guy"? This is the experience of every programmer I know. What difference does it make if they run Linux, yes stuff will break but we've been fixing stuff breaking anyway.
