Whether it is useful or not skates pretty close to a utilitarian argument which has little to do with privacy, it is quite possible to violate privacy and get some use out of it but it shouldn't happen anyway.
The privacy respecting part here seems to be handled carefully, I'm not sure if it is opt-in or not (in my opinion it should be) and the payloads appear to be benign, but, that could still go off the rails if there is a bug in ABRT.
In principle I want my machines (desktops, servers) only to initiate network calls and to respond to network calls that I allow. Outbound firewall rules are there for a reason.
