Media companies that also sell personal data
I think the main harm identified here is summed up in the line;"The truth is pay-walled, but lies are for free"It's not what information is or isn't collected. It can be valuable,
and great social good can come out of so-called "big data". And we
can, as a society, sensibly decide what is allowable in terms of
prediction and prejudice (which are essentially the same thing in this
context).The problem is utility asymmetry. Having a few for-profit corporations
own and trade our data is a societal catastrophe in the making, and
can only tend toward fascism.
