Disagree. “Necessary to provide the service” means whatever they want it to mean. If they deem it necessary to monetize your data so they can offer you their service “for free”, that is well within their right to do. The fact that you " retain all rights" just means you can use your data too without asking Cloudflare for permission.
No it doesn’t. The first sentence does not state anything that is not already clarified by law. Hence, it adds zero value to the actual meaning of the paragraph.
Same thing, you can say if I redact the first two sentences from the quote I’m being disingenuous, but really I’m just trying to get one over on you by making you feel like you have some control in this when in actually you do not.
