Its not. I explained in the below comment why Cloudflare and others like them helps you decentralise. And other benefits.

Cloudflare is literally helping the internet to federate on a tech level. All our services like youtube Videos, instagram content, reddit and other fast access content are quick and smooth bc Cloudflare and similar companies temporarily store data at locations that are close to you.

Without them all your data would be stored in few central locations. Not only would it be slow as fuck, they would also be more vulnerable.

Also Cloudflares other main products are cyber security. Which is good for smaller federated entities for obvious reasons.
