It’s just one more annoying little thing to go on the big list of items to be corrected when setting up a systemd-equipped system, but more importantly believing that it’s acceptable to just leave it there demonstrates extremely poor judgement to a degree that makes many of us doubt the trustworthiness of the entire project. Perhaps in 2013, or whenever the decision was initially made, substantial numbers of people were sufficiently clueless as to think that adding in the possibility of inadvertently having your system quietly direct all its DNS queries to Google was better than the more obvious alternative of not doing so, but after everything that’s gone down since then it’s quite hard to imagine why anyone would stick up for such a bizarre point of view today.
