Since when did PC become synonymous with "Microsoft Windows"? It seems to me that everyone is doing it, even old timers who should know better.
Writers pay attention, I've come up with some alternatives;
ICx86HW: Intel compatible x86 Hardware (which would still imply Linux support, among other operating systems, just like "PC" does)
MWXP+: Microsoft Windows XP or later (you'd probably need some trademark symbols and (R) characters in there)
IDCTIPCM: I don't care that I am in the pocket of a corporate monopoly
Probably the second one. Or you could just go back to saying "Windows", and everyone would understand perfectly well what you meant. "PC" isn't perfect, it's not even close to accurate. It's highly deceptive and flat out wrong. Of course, those of us at the pointy end of the stick are already aware of your hypocrisy and can make informed choices despite your idiocy and obvious mismarketing.
But those who are not even aware of the stick being pointed will keep on living in blissful ignorance because you perpetuate the status quo, dumbing down society to the next level.
What's the rate now? Minus one level per day? At least since 9gag and 4chan became a "thing" with the young ones. Where are the days of somethingawful - where UNIX, DOS and Windows programmers knew how to tell one operating system from another? How long until we're at Idiocracy levels? Let Luke Wilson be your Jesus.
