Start with this tweet from Paul Haddad, maker of Tweetbot:
Not sure if its a new App Store rule, or just whichever reviewer we got, but they requested that we remove Tweetbot 5 from sale within 30 days of Tweetbot 6 going live.

And by request I mean wouldn’t approve until we agreed. Was going to anyways, but just FYI.
Saw this, went to the App Store, typed in Tweetbot, found nothing but a long list of competing products. No Tweetbot, no Tweetbot 5, no Tweetbot 6.
Searched again right before I wrote this, found hints (the grayed text completion that suggests as you type) for Tweetbot 5, which took me to a competing Twitter client’s page. Tweetbot 6 took me to an “early access” page.
This is certainly confusing. Michael Tsai rolled up a number of clarifying comments on his blog, worth a look if you are a dev interested in this issue, especially if you are exploring the possibility of moving to a subscription model.
