That's not something Cloudflare decided, though. It's just a fundamental limitation on how the Internet works. The destination IP needs to be visible to intermediate nodes so that they know how to get it there, so the only way to get this kind of privacy is for lots of services to be hosted behind the same destination IP. And keep in mind that it's not Cloudflare exclusive. Any similar service that does large-scale name-based virtual hosting will also give you the same privacy benefit with this.
