An excerpt:
Like the author, I'd like very much to run a free mobile OS too, however, and how the article shows, this is still a hit-and-miss process; some will partially work, some others either will not, or are a pain to try to make them to.In 2020 my hopes came true when multiple nearly-ready mobile OSes became either available or usable for regular use, and now I am the owner of a LibreM phone and PinePhone, as well as having tried several Free Mobile OSes. To date I've tried UBPorts, postmarketOS, PureOS, Mobian, /e/, GrapheneOS and now CalyxOS. UBPorts, postmarketOS, PureOS and Mobian are each different but we can roughly classify them as "Linux-based " and GrapheneOS, /e/ and CalyxOS are all Android-based. These are only rough classifications since the term "Linux-based" can mean anything that runs the Linux kernel and Android technically uses the Linux kernel. Nonetheless I'll be using this classification system for reasons that will become clearer in the next section.
