Twitter officially bans all third-party clients, forcing people to use its own apps
While there has still been no announcement, Twitter has updated its developer agreement so that third-party clients are now prohibited. Over the course of the last week or so, we've already seen the likes of Tweetbot and Twitterific rendered useless after the company blocked API access.
Twitter later said that it was merely enforcing long-standing rules, but failed to provide any details or clarification. But now a new developer agreement has been published that slaps a ban on the creation of, "a substitute or similar service or product to the Twitter Applications" -- in other words, third party Twitter apps are now forbidden.
Twitter confirms that it is deliberately blocking numerous third-party clients
Users of various third-party Twitter clients have been frustrated over the last week as their chosen apps stopped working. There was speculation that Twitter was blocking apps on purpose, with internal communication appearing to substantiate this.
Now we know for sure that it is the case, with the company confirming it in a tweet. Twitter says that it is merely "enforcing its long-standing API rules", conceding that this "may result in some apps not working". But there is confusion from app developers who say that Twitter is not revealing which rules it is referring to.
