Tweetbot 6 with subscription model: Apple requires removal of the older one-time purchase version from the App Store

Tweetbot has enjoyed a certain popularity among Twitter users for years because of its practical features. The app was previously available to iPhone owners in the iOS App Store as a one-time purchase. This is over with immediate effect: Tweetbot 6 is offered free of charge, but can then only be used to read posts. If you want to send tweets and use other functions, you have to take out a subscription via in-app purchase.
