Advertising considered as a
cancer
on society.
I largely agree. I think that the worst aspect of today's advertising
(and the reason there is so much of it) is the collection of personal
data — but the article identifies other ways in which
advertising corrupts society which don't depend on knowing anything
about who sees the ads — for instance, paid-for articles (I
won't use the euphemism "sponsored" or the derogatory term "content"
for this) and individuals who are paid to insert advertising into
their lives as "influencers".
However, if you are like me, you probably wouldn't notice what brand of
coffee appears in your friend's photo, so it would fail to exert any
influence.
