if Unis are keen on online lessons, they should provide it at the cost of an online course such as the OU (which includes some weekends where people meet up, have some teaching etc...)
OU charges the same tuition fee as every other English university.
My point was not that universities should or should not continue to offer online learning to students. My point was that it's impossible to generalise, particularly if your experience/knowledge is based on the anecdotal evidence of your DCs' current university experience.
Universities are complex organisations, which are research organisations as well as teaching institutions. We have significant numbers of international students (who subsidise Home students' fees) - some of whom may not be permitted to travel to the UK by the UK government or their own government.
Universities are like small towns - mine has around 20,000 undergrads, and several thousand postgrads, plus several thousand staff of all sorts, all ages, and states of health. We have CEV undergrads, and CEV tutors or student-facing admin staff.
My university has taken its duty of care to its staff and student' health very seriously, and continues to do so.
Just because any poster, or her DC, are happy to take whatever risks they want to take re COVID, doesn't mean that it is OK to impose that level of risk on everyone else.
This is the thing that we have learnt from this pandemic: it's not about the risks we as individuals take - it's about being mindful of the fact that the choices we make impose risks on others.
