Who else's fault would it be that Windows requires 3x more support?
The vendors who supply the 3rd party drivers.
Macs are more reliable/require less support because there is very little a corporation or end user can add to it, to customize it beyond built-to-order. I've been building my own PC desktop machines for decades and I have had very few problems because I tend to carefully select the parts and use "better" rather than "less expensive" parts. However my PCs are sort of anomalies in this respect. When helping friends and family "debug" their PC problems the BSOD was usually coming from a 3rd party driver, from a second tier low cost vendor. By maintaining a higher degree of control Apple is less susceptible to such problems.
The secondary benefit of my BYO approach is that I have had very few Linux compatibility problems over the decades.
Oh, and Windows has been running natively (dual boot) very reliably on my Mac laptops for many years now.
