Believe it or not, I blame this entire incident on Google, not LinkedIn.
Reasons?
a) you sign in using google. That is actually a REALLY GOOD PRACTICE because it gives you lots of benefits of oauth (I can de-authorize an account).
b) you only have the one password to remember, which is good for most people.
Why it's bad? Because when signing in, the other side can ask for details from your account and the best you can do is say "yes" or "no" and if you accidentally said yes, it's plowing though user preferences (something most people can't do) at google.
What should happen instead? An intentionally slow experience.
a) user clicks the sign in with google+ or whatever.
b) user is presented with option "allow/deny access for XXXX domain to log in with your credentials"
c) user is now presented with (all default off) options to allow sharing of data. There is a big message up top saying "these options are not required for you to log in with your google account. You may lose some functionality, but will not share any extra data with the 3rd party"
