"Seriously, why is it such a confusing prospect to Linux users that Linux is difficult?"

Because honestly? It really isn't. A couple of years ago, maybe it was hard, but now, Linux is easy to pickup and learn; so easy even someone like me who has zero programming/coding skills (not my profession) and still kinda thinks typing stuff into the terminal is basically black magic was able to pick it up and adopt it with very little hiccups and set it up for my ma on a seperate computer with no problems on her end. Unlearning Windows? That's the hard bit, especially if you go into Linux (or even Mac, as was the case with me a long time ago) thinking it's Windows with another skin instead of different beast althogether that has it's own quirks one needs to get used to, just like with anything new (and just how the majority are used to Windows's own quirks). That's where you'll start having a bad time.
