I would only point out that most hardware problems are due to vendors refusing support of any OS except Windows. If they didn't support Windows you would see equal problems there. I know there has been a lot of contention with nVidia over the years, not so sure about others.

Also, linux does take direct control of all hardware and runs it hard. If a vendor claims their devices can run under certain conditions then Linux expects it to actually perform that way. Many vendors exaggerate their claims though and it's quickly discovered that their devices cannot actually perform as expected on the general hardware sold to the public. Nobody is surprised, and the linux driver admins eventually make those features optional so you can test the specific device to see if it lives up to the vendor's claims. My nVidia GTX 1050 has been running well for me though.

Otherwise I agree that yeah, a lot of faults come down failing hardware. In my case the same machine that constantly blue-screened under Windows worked fine for many years under Linux, and I'm one of those who really push the hell out of my computers. Coding in Visual Studio while also having a bunch of other windows open for reference on my current project, on a machine that only had a gig of memory? Yeah I expected a lot. And moving forward to today, I have dozens of windows open to browsers, spreadsheets, terminals, image editors, and 3D modeling software. Surprisingly I currently have over a gig of free ram right now (on a machine with 16GB) but I'm usually closer to a half or quarter gig free. My machine is pretty clean right now because it rebooted a month ago from a power outage during a storm, so we'll see how it looks in another couple months.
