It seems to function just fine (I'm not talking about Proctorio), and it doesn't invade privacy any more than the Zoom-based tutorials, which is barely at all. It is also better than any other alternative I know of, many of which have been tried already and found wanting. Privacy is not a god to whom all things must be sacrificed. All education involves losing a little privacy (in person people will know what you look like, where you're from, and many other things that are hidden for remote students; really they have more privacy than any others), and the fact that software is involved doesn't suddenly make things worse.
The software we use is easy to remove, and students have a lot of software installed on their private machines already, some of it more invasive in software terms (e.g. games with anti-cheating features). I have more qualms about the software and the privacy implications than the students do, and I'm resigned to it for now; the students just went ahead and installed it without comment.
