Apollo is similar! iirc the only “functional” feature locked beyond a paywall is submitting posts (which you could argue is a pretty big feature to lock away). But I think the majority of users rarely submit posts, and the “pro” tier was just a one-time $5 payment. I found Apollo very intuitive to use and very minimalistic; there was very little fluff to distract from posts and comments.
