This is like saying you're self-hosting a game server because it's not hosted on the developers' server, but on the server of some other random third party you're paying to run it. No, self-hosting means you run it on hardware you own. Cloudflare is no stranger to redefining completely established terms for marketing reasons (see 'Cloudflare OS'), how about we stop buying it every time?

But it’s not self hosted like in self hosted.

Why add a false feature claim if the true features are cool enough?
