From a dev perspective Facebook is a piece of shit, if someone like me get stuck with things like creating a page, what would be like for someone who's not comfortable with tech things. They have the ressources to make it Apple like UX .....

Ease of use is not the only possible design goal. Sometimes you benefit more if you make things difficult.

@electrineer indeed. Experienced users could be wishing seeing more complicated interface, because it allows them to do things faster than in simplified interface that hid all complexity.

Example:
Windows 7 (experienced user oriented) Vs New Windows versions (dumb user oriented)

@darkwind customer success is also not the only goal if your customers are also the product.
