Typing this from Sync for Lemmy. Love it already! Feels right at home.

I do not mind the subscription costs for the premium version. Yes, in a perfect world a lifetime purchase would be nice. But this isn't a perfect world. Lemmy isn't a casual game that can be considered "done" once it's developed. No, Lemmy and the Fediverse are new and unfamiliar and it is likely there will be significant chances to the ecosystem and this development effort for the developer.
