Could you please write the same comment, but without the namecalling for what seems to be an honest mistake?
Good Lord, for all the talk about the Fediverse being a nicer place than corporate-controlled social media, comments like yours really show how that is very far from the rule.
Using a CDN does not come without downsides, though. Cloudflare itself is becoming another "too big to fail" entity of a system that is not supposed to depend on the resilience/capacity/budget of any single actor.
Personally, I'd rather see a tiered architecture for data, where servers are only responsible for guaranteeing the data from actors on their own servers, but everything else stored in a distributed, append-only stream of data. This would make a lot cheaper to run individual instances and would allow clients to obtain the data from multiple sources.
