Equally, it's accepted that a bunch of today's Gnome apps have title bars with controls inside them. I don't think it's that jarring that if you don't click on a control accurately and then start dragging the mouse, you're going to move the window.
Though there are already TONS of critiques to GNOME (hell, even I have written some stuff about them here) and so much has been said about it that saying something else seems like a waste of time in my humble opinion. Its devs won't change their mind because they have a laser-sharp vision of what they want to achieve. Its users won't change their mind because they like it and feel at home using it. We the people that don't (or no longer) like it won't change our minds either because it can feel really strange, confusing and even limiting.
It's been more than 10 years since they went to that route but they will do little to nothing about that because, as the author correctly asserted, "it's also a project that's very vocal - opinionated, as the saying goes - about how to do things." So either you like the GNOME way of doing things or you just can go somewhere else. Which, again, it's a bit contradictory taking in account their "Our software is built to be usable by everyone" motto.
Super + right mouse anywhere in the window presents a window management menu, including resize/move options
