Maybe not yet, but the simple fact, that there even is a Cloudflare "analytics", hints at a direction, in which this will probably develop. Some people inside Cloudflare will think "If only we could sell our analytics data, we could profit more!" and then they might just do that. The temptation is huge for them. Lets be realistic. They are not all idealistic developers at Cloudflare. It is a huge business with lots of unethical people working at it, like in many big businesses. At some point some internal pressure might overwhelm a minority fighting against it and the change will happen. Perhaps it will happen step by step, slowly boiling the frog.
