There are many great open source projects that are amazing but the model is to avoid developing critical core functions and put them as a separate paid system. Abusive imo
I used Apollo for many years. Stopped using it two years ago because a known bug related to when scrolling feed suddenly you get a error that there is no more content. A lot of users reported it and what dev only does to to make more decorative content to buy. The dev was really good improving the app but I don’t know what happened there around years ago.
