I doubt it's nostalgia, even though i m old too. It's just a lot more efficent and faster to use, mouse and keyboard-wise. I often think to roll back to my windows 7 as a more sane desktop environment.

Some of the biggest offenses i 've seen are google's web apps. Total loss of hierarchy and replacement with elusive self-hiding buttons, even when it's clear from their use case that they should never have been hamburgerized. I 'm pretty sure, even in mobile, they are making the UX worse.
