GUIs used to be designed by power users, who would start with an advanced design and strip it down to a simple version the average user could use. Now GUIs are designed by average users who have no idea what to do with advanced features, because they're stuck thinking about the GUI as an average user does.

Power users understand many different levels. Beginner/average -> professional -> advanced -> power user. But the average designers nowadays only understand two things: average, and everything beyond that. This is why professional, advanced, and obscure features are all just one long-press away - they literally have no idea which category each feature falls into, so they're all equally valid.
