I think there are two types of people on here.
One type live their lives on Facebook, they are happy for friends/family/acquaintences to have a blow-by-blow account of their lives, to share photos and to keep everyone updated every day. They don't care about a Facebook button - why would they, most of their life is there for all to see anyway.
The other type doesn't use Facebook (except possibly for keeping up with a few friends, sharing photographs, in which case they have very high security on Facebook). They don't tell everyone their everyday business. They like being anonymous online.
Some of the latter have very real and valid reasons for being anonymous (DV, SN, difficult family/ex-partners/children/jobs with security risk, etc etc).
Those people really do mind.
Unfortunately the first group don't seem to be able to put themselves in the position of the second group. They say "Who cares?" but what they really mean is "I don't care and I don't give a shit about you"
