Is Nostr.build a true Nostr client?
Furthermore, it requires a pro account for pdfs, which is a paid account. So let me get this straight… As a content creator, I need to post tons of free content that is free and open source based on unpaid labor while using paid services before asking for funding? 🥴😑😳😅
