Of course lots of designers make the wrong decisions about which functionality they have openly on display vs. which functionality they hide away in menus. They often lazily shove a new feature in a menu, rather than find a way to properly integrate it with the design of the app. But that's not the same as saying "menus=bad".
The traditional horizontal menu bar with multiple consistently-titled menus is a system that has worked very well for decades. For developers and UI designers, it's generally quite obvious where menu items should go. For users, it's generally obvious where the developers would have put the menu items for some specific functionality.
The Chrome-style single-obscure-menu-with-everything-poorly-organized-inside-it approach throws all of this away. It results in the worst of all trade offs. It's harder to find, the menu itself is an inconsistent jumble, the amount of functionality within it is less, it's not worth gaining a small amount of screen space for the inefficiency such a broken menu system brings, and it's just plain harder to use. It really is bad in every way.
