This. I regularly use Facebook mobile website on my quite powerful smartphone. Basic UX functions are lacking there though they are possible . Facebook engineering is over-engineering the whole application across multiple platforms but can't fix many usability issues and add missing features on many of them. Finally a like/action, comments around a few hundred "friends" with text, audio and video shouldn't require that much effort. I mostly suspect they over engineer because they can! namely too much money can buy too much talent and skills. But maybe they don't need that much.
