Last week, many independent Twitter apps abruptly stopped working when Twitter shut down the necessary API without explanation. In the latest news from Twitter's slow-motion implosion, Engadget discovered that Twitter has now updated its developer agreement to exclude third-party clients. That makes the appicide official, to the extent that anything coming out of Twitter these days is official. In response, The Iconfactory formally announced that it has [4]discontinued Twitterrific for macOS and iOS, and Tapbots published [5]a memorial to its now-defunct Tweetbot app. Twitter may be able to deliver more ad impressions through its native apps, but this move may finally drive many long-time users who relied on apps like Twitterrific and Tweetbot to Mastodon.
