I would say it is ok to have a trusted and centralized server making recommendations, displaying lists of interesting content and curated home feeds, but the actual act of fetching the data from people you follow must be done on the client-side and using something like the outbox-(gossip)-model thought, otherwise there is no censorship resistance at all.

I like this way of grow own account by searching users/contents on different platform and then consume them in a fully decentralized way. Clients should offer easier way to mass import npub/nprofiles with a simple copy/paste.
