Their "we're only a neutral pipeline" spiel is complete bullshit and I'm glad they are being held accountable for it.
(Short version: They are not neutral because they provide a paid service for the websites they host.. Yes, in some cases it's a free service but in that case you are still "paying" in good publicity. The fact that no money changes hands doesn't suddenly make them a neutral party.
They are also absolutely a hosting provider. Even though they don't host the central, permanent, authorative data of the sites themselves, they still host plenty. They store images, code, stylesheets even complete pages in their cache. The data is on their servers, being pushed onto the internet from their ip's. They host the DNS. They can even host some business logic with their page rules.)
Without going into whether the rules that apply to webhosts are fair, it is a very good thing that Cloudflare is being held just as accountable as any other service provider. Their IP's, their responsibility just like any other party.
Edit: Those downvotes came quick. Care to comment on why you think Cloudflare should be held to a different standard than a traditional hosting provider?
