What killed me it was Twitter killing developers apis: no more interesting apps than theirs. It sucks big time. They're also screwing the chronology, sometimes you get the latest tweets (most interesting) and sometimes they switch you to Recommended, which, normally, it sucks. Let me browse chronologically as it was in the old days.
I recently wondered about this, from another angle. In a way it was "weird" that they had an API, given our times. I.e., it was different: imagine if FB/Instagram/WhatsApp had an API. (I think it would be awesome, but it puts into perspective that it was weird that they had one imo)
PS: I keep a few selected apps from this era on my phone. Once a year I open them and admire them in their data-less beauty. (Favourite one: Partly Clouded) Let's call it software shinto.
