The company is focusing all its efforts on Twitter-owned apps, claiming that only 1 percent of third-party developers use the "two legacy developer tools." That means some non-Twitter apps won't be able to have automatic tweet streaming, which means those developers will need to update their code to adjust. Tweetbot has already fallen victim to the changes, and users of the app will no longer get real-time updates, be able to use the Apple Watch app, or get push notifications for likes, follows and quotes (mentions and DM notifications are delayed by one to two minutes).

Twitter's Senior Director of Data Rob Johnson tweeted out an internal email that explained the reasoning behind the changes to employees. In the announcement blog post, Johnson admitted that not everyone is happy about the changes. "We know some of you don't like this more focused approach," Johnson wrote. "There are good reasons you love the various Twitter apps you have used over the years, and we're grateful for the developers who build them." He says the company is still committed to its developer ecosystem and that it "continues to invest in TweetDeck," which is now owned by Twitter.
