Third-party Twitter clients like Tweetbot and and Twitterrific were critical to the success of Twitter and their users are some of the company's most valuable.

Both deserved better than to have the Twitter API shut off on no notice with no explanation. My thoughts and some history over on @macstories: https://www.macstories.net/stories/twitter-intentionally-ends-third-party-app-developer-access-to-its-apis/

Twitter Intentionally Ends Third-Party App Developer Access to Its APIs

Late yesterday, The Information reported that it had seen internal Twitter Slack communications confirming that the company had intentionally cut off third-party Twitter app access to its APIs. The shut-down, which happened Thursday night US time, hasn’t affected all apps and services that use the API but instead appears targeted at the most popular third-party

@johnvoorhees @macstories This is very disappointing. I had been hoping this was all some sort of technical problem rather than a corporate course change. I'm very fond of Twitterific. I'm not sure I can go back to using the default Twitter app and the constant ad spam. I'm one more step closer to giving up on Twitter completely. Thank you for the heads up.
