Or you could store signed exchanges on platforms like Dat or IPFS and get real decentralization.
Right, the point is that anyone can serve the content through any platform, which is why it allows decentralization. But I just don't understand why people are hanging so tightly to the idea that a URL is a direct path to a server, because that just isn't true.
Isn't signed exchanges basically CDN's without having to setup DNS? It's in theory no different than using CloudFlare to serve your content, except any CDN can just serve it without giving them access to your domain.
