The range of institutions called universities in the UK is large and I think you are conflating properties of one end of the range with properties of the other.
I disagree. Oxbridge, LSE, Edinburgh, etc appear equally as susceptible. In fact in top London universities it seems to be worse - prestige attracts more international students.
I also agree in the sense that there are less prestigious universities that appear to operate as if they are almost Chinese/in China.
I don't need to divulge personal information to make a point. See comment below. I think it is pretty apparent to anyone with any interactions with universities in the U.K. and in other countries. The fact that it is now a geopolitical tool for China is pretty concerning.
