Around two or three weeks ago Tweetbot, purchased eight or nine years ago and my favorite Twitter app by far, stopped functioning. At first the alerts called it a temporary or pending situation. I didn’t investigate or even focus all that much on the problem — I figured it would eventually shake out. A few days ago Tweetbot began working again, and then not. Now it’s permanently neutered. Elon Musk has deliberately zotzed all third-party apps. Fucker.
