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 Do we know that it was intentional/malice? Or is there still a possibility that it was incompetence?
@rwzh I Trust The Information's reporting on this. They say they've seen internal Slack messages that it's intentional
@johnvoorhees I guess that's not surprising.
Probably reevaluating things with a shortsighted: "monetize or kill?"
