I am not entirely a fan of the current (later Doctor) series, but still, that has to be a summary by a viewer expecting and finding the worst - confirmation bias in short. First off, and most glaringly, Gavin Clark seems to have missed points, both in this and other episodes involving cybermen that show they aren't precisely perfect. It is clear for instance that the very LAST cyberman in the episode was the revenant of Lethbridge-Stewart, who saved his daughter or grand daughter - I forget and don't really care which. So it wasn't just Danny who was not fully taken over by the hive mind of the cybermen. L-S finally gets a salute from the Doctor too.
Second, and far more potentially important to the storyline (or tangle) is the fact that we DO NOT KNOW what the doctor saw at the coordinates provided by Missy. The audience sees straight out the door into empty space, the Doc is looking down and to the right at something not shown to the audience. We get to look out the door and see nothing, but never get a glimpse of what the Doctor sees. So, was his rage in that scene because he still doesn't know where Gallifrey is, or because Missy, the reincarnation, more or less of his "childhood friend," actually DID tell the truth. That friend, who clearly expressed the need for HER friend, is now gone and the Doctor failed her again.
Third, it is also clear that we still really have no proper clue as to just who (or what) Clara Oswald really is. She was a Dalek once - more faulty technoology, a Victorian governess come Torchwood associate, and once more a school teacher in 21st C London. She has already been dead twice and yet seems to have the endurance of the Energizer rabbit - or a Time Lord. I vote she's really the Rani.
