I find this entire rant to be utterly ridiculous. Everyone is entitled to their opinions, but I do not think there is anything wrong with Finder. It's honestly no worse than any other file manager that I have used. I much prefer Finder to any alternative I have tried.

I really enjoy the various keyboard shortcuts [1]. I honestly wish more file managers had some of these features. I probably use "shift+command+g" the most. It's so nice being able to jump through Finder like changing directories in the terminal.

Honestly, for more complex tasks, I actually just use the terminal anyway.

And unlike Windows, the obscure shortcuts are discoverable by holding the modifier key down while a menu is open.
