From what I can tell this seems like a classic example of devs just not communicating. On mobile I don't see any mention of a "Pro" option on the front page, and I don't see any "essays" about it either. Perhaps its buried in one of the essays, or maybe it's been communicated elsewhere, but if you're planning to launch a paid service around an open source app it's really a good idea to communicate the intent clearly BEFORE it's launched. If it just comes out of no where it feels to the community like they're getting rug pulled. On top of that terms like "Pro" and "Premium" and "Plus" have been ruined by predatory subscription models. Similar thing happened to Hyperland a while back and I think a lot has to do with the language used. That said, the terms seem perfectly reasonable, and a life long license is great. Though 300 dollars is going to cause sticker shock to a solo dev I think. Edit: To the devs I would recommended adding something like "All features of Datastar are free and open source. If you would like to support us consider donating or purchasing a lifetime license for access to <insert stuff here>", to the home page, maybe under the intro to the project" And drop the "Pro" branding.
