Apple has a long history of knowing better than its users. "You may think that you don't want to share this info, but we know that, deep down, you really do."I have seen this exact behavior going back to El Capitan (and posted about it here). On Mojave, I don't have a permanent Little Snitch rule but I seem to recall one or two instances of attempted connections to radarsubmissions, which I blocked. So maybe Apple seemingly going behind our backs may be less of an issue, but I believe it still happens (at least in this regard).
