It’s not complicated – it’s familiarity. I have used Linux as my daily driver for quite a few years now, so the moment I read your problem I was already crafting the find / mv command in my head as how I would resolve the problem. I am more familiar with it, it doesn’t feel complicated at all to me – I’m telling the computer to find a pattern, and then move the results (literally the name of the commands!). That feels really straight forward to me because I’m used to it and it’s in my comfort zone. Because I don’t use Windows much (really only at work, and only to run Word or Excel) it actually took me a second to figure out how I would do it in Windows (at first, I was thinking a Powershell script), and I didn’t even realize that when you search in Explorer you could bulk-move the results (although I should have, that’s pretty logical functionality and like I wrote I do use Windows at work albeit in a non-technical way!). Essentially, often when I have to do anything even marginally complicated on Windows, I feel the same frustration you do because it’s not intuitive (to me) and it would be so much easier if I was only using the system with which I am more familiar.
I won’t suggest that the Linux console is easier for most users, the way we use technology in our lives (and not just desktop processing) automatically makes the Windows interface more familiar to most people. I do totally recognize that if we do want Linux for the masses or whatever cute phrase is being used to promote Linux desktops for mom and dad and business then we have to adapt to what most users are familiar with.
