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.

@johnvoorhees Do you have any idea of the usage stats for the apps that were blocked? For example, how many Tweetbot DAU are there that may now become disenchanted with the official app?
