Oxford University's measures to protect students studying about China
from repression by China: they submit their homework anonymously, and
recording those classes is forbidden.
The precise extent and depth of this anonymity are not clear in the
article. If it means that their teachers don't know their real
identities, that is surprising but may be necessary — I won't argue
with it.
If it means simply that their identities are not associated with
their work in some corporation's cloudy data base that the school uses,
all students deserve that kind of anonymity, on general principles.
Don't dox anyone to a company.
The prohibition on recording classes seems to be necessary in this
case, but it has the unfortunate effect of blocking the one way you
can fully participate in a Zoom class without running Zoom:
find someone willing to make a recording of it, one way or another,
and watch that video (either in real time, or later). (You can participate
in audio by phoning in.)
This could still be done if your friend sets up a webcam on another
computer pointing at the screen, and transmits a stream to your
machine. But that is extra hard since webcams are expensive these
days.
