Nearly everyone forgets how hard windows was to learn initially.
I spent the better part of a child hood and the first 10 years of an IT career learning it. Does that sound like a simple or easy system? Conversely I've spent slightly less time but an equal 10 years of an IT career learning and supporting Linux. I've only recently in the last 3 or so years started to feel like I truly grasp Linux and started using it as a daily driver on personal machines.
I now find Windows absolutely horrible to work with. All the nonsense MS foists on it's users. The inflexibility. The weird choices. The licensing nonsense.
The bottom line is not that Linux is harder. It's that Linux is different and different is scary and uncomfortable. Different is hard, not linux. People are lazy and creatures of habit. We like familiar. Few of us actually enjoy the work of learning something new that isn't easy. If we did more of us would probably be pilots or engineers or whatever hard thing to learn you want to choose.
If you're into computers and you still find it hard or constraining keep at it. The Ah, ha! moment is coming. There's a paradigm shift in thinking you'll hit and suddenly you'll get it. When you do you'll find it's magnificent and powerful and freeing.
