What in the world was Adobe thinking?

Our shop recently upgraded our machines and software and, whoo boy. I've been wrestling this awful thing (Acrobat DC) for a few months now and have honestly never seen anything quite like it.

This iteration of Acrobat has to be the most insane design decision I've ever seen. Forget the abominable, counter intuitive interface that nobody anywhere asked for. Forget the clunky navigation and long, drawn out tool and workspace customization needed to make it workable. Forget the constant crashes when I want to view separations and that they often don't accurately reflect the actual inks anyway without refreshing. Forget that if I convert a file to greyscale, it will make my 100% blacks 94% no matter what gamma or boxes I check.

Forget that if I try to select more than one object in output preview, it adds a sticky note instead. Forget the thin white lines that show up on my and my customer's screens that don't print.

Aside from this ridiculous interface, my main gripe with it is that tools don't do what they're supposed to. Sometimes the select tool lets me, you know select an object. Often it does not. Marquee select? Forget that. It just draws a transparent blue rectangle that doesn't select anything. When I am lucky enough to get a selection made and navigate to "edit object"/"edit using", I will open that piece of the pdf in Illustrator or PS, edit it and then when I re-save my pdf, the edits do not show up.

I could go on. I am honestly baffled at the thinking that led to this decision. Having to learn drastically redesigned new interfaces is only not needed, it hampers productivity - the opposite of what it is designed to do. Is it too much to ask to request that Adobe simply collect our money every month, tweak the bugs and just polish the product? I am not getting paid to re-learn software I a was hired to be proficient in.
