It can be captured, only by consolidation of clients, and full stack ones at that. The most important thing is for there to not be a single dev or company both building a client, relay software, running a relay for its own users, and a blossom media hosting. The most important of those is client centralization and market share. Clients will never be fully equal. Some client will be better for most people. The natural way to limit this is to really discourage multiplatform apps. No matter how much amethyst gains market share, it can't surpass the percent that uses android. That's a great thing. Honestly the most important thing for decentralization was done in the beginning by nostr:nprofile1qqsrhuxx8l9ex335q7he0f09aej04zpazpl0ne2cgukyawd24mayt8gprfmhxue69uhhq7tjv9kkjepwve5kzar2v9nzucm0d5hszxmhwden5te0wfjkccte9emk2um5v4exucn5vvhxxmmd9us2xuyp by not having a first party client or node implementation. As long as there is an "official" app, it will gain too much market share from normies to leave room for any decentralization. When it exacts policies and decisions that any client and relay need to, it will be the de facto rules of the protocol.
