Can't decide if you are being sarcastic or not. But I'll reply assuming its a serious question.
Tweetdeck was created by a third-party developer in 2008. It was and is so popular that Twitter acquired it in 2011 for £25 million.
And then Twitter started slowly shutting down its apps, all the mobile versions of Tweetdeck (Desktop, iOS and Android) were suspended and removed from respective app stores. Only keeping the web version alive altered and modified by Twitter. Tweetdeck also had Facebook, LinkedIn and some other social networking service integration, those were removed too. Tweetdeck is pretty much the best Twitter app for advanced users. Now its alive but we never know what Twitter plans to do with it.
