I'd call it abandoned if it didn't fit the platform standards, if it was buggy, if it didn't run on some new devices…
This update in September is enlightening:
Added support for iOS 11 password autofill.
You know which other OS introduced system-wide autofill suppport? Android Oreo.
I think it's safe to say that Instapaper is abandoned on Android.
I'm a heavy Instapaper user myself and was always disappointed with the quality of the official Android app: it runs terribly slow, some articles don't even show up, no image thumbnail, etc.
My app doesn't have all the feature from the official app yet (I'm starting simple), but I'm very open to feedback.
