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 Twitter clients, including Tweetbot by Tapbots and Twitterrific by The Iconfactory. More than two days later, there’s still no official explanation from Twitter about why it chose to cut off access to its APIs with no warning whatsoever.
To say that Twitter’s actions are disgraceful is an understatement. Whether or not they comply with Twitter’s API terms of service, the lack of any advanced notice or explanation to developers is unprofessional and an unrecoverable breach of trust between it and its developers and users.
Twitter’s actions also show a total lack of respect for the role that third-party apps have played in the development and success of the service from its earliest days. Twitter was founded in 2006, but it wasn’t until the iPhone launched about a year later that it really took off, thanks to the developers who built the first mobile apps for the service.
