Yes. But blossom servers are a common http server. I don't see much difference in everything being on the same site. Because if there is any censorship it will be on the main domain and not on the blossom servers.

If only the main domain itself could be made uncensorable... 😏
yes, domains will be taken down but files / blobs are addressed by their sha256 hash which means they have the same ID across all servers. so when a server is taken down or a blob is removed from it you can easily go to another server and ask for the same blob
for example here is the same image hosted on multiple servers
And you can verify they are the exact same image because if you download them and run "sha256sum
