TweetBot developer, Tapbots, has decided to create new versions of its app, and charge separately for them, even if you purchased the old app. The older version still works, but it's not on the App Store anymore so you can't easily restore it. The new version has more features and costs more. Tapbots is taking an approach more closely aligned to how hardware or even automobiles are sold.
