I wrote about this problem here before: View article → Ideally, in 44billion or a 44billion-like app (which should use blossom URLs to refer to apps instead of Nostr events -- or the Nostr events should reference blossom URLs) each app is a hash, and in theory you can give it any name, and once you have that hash and the associated files downloaded you're not prey to weird changes made by the author anymore, or the app going down, or the app starting to hijack and damage Nostr or decentralization, you can keep using the same app. Of course you can always opt in to get the latest releases, but, more importantly, you should be able to set someone else as the "official" maintainer of a client, and your friends can notice that and do the same, so the original maintainer can be semi-automatically ignored if he decides to go rogue, and their fancy domain name won't help them keep tricking users anymore. It's a long shot, but a necessary one.
