> Why is this not an acceptable solution for CSP? If tracking tools start using CSP for this, they'll be added to the filter lists, just like any other tracking script. We're not asking uBlock to block all third-party requests on the off-chance it might be an ad or tracking service This is a good question! When a new technology arrives that allows tracking, I prefer uBlock default to blocking it. Advertising/tracking companies pursue the bleeding edge in their cat & mouse game; this way the barn door is closed before the horse leaves (two too many animal analogies?). I do understand that others will pursue a different choice, and encourage disclosure by those doing so because money is on the line. The discussion regarding CSP has resulted in a change in uBlock's default behavior which I will take into consideration the next time I re-evaluate which ad blocker to use. PS. In case it's not clear, I originally commented: >Personally I would prefer only same-origin reports. PPS. This is a much jucier target assuming it works when JavaScript is disabled.
