Social logins: Google more accepted than Facebook

This doesn't surprise me at all. I basically always choose to login via Google rather than Facebook when given the chance, even if the service is only requesting bare minimal permissions when authenticating via FB. If given the option to log in via fb or create a new account, I'll usually just pass altogether unless I feel the need to create an account. I believe Quora was the last service I used FB login for, and I deleted that account a while ago.

For me at least, a lot of the overzealous apps from a few years back that requested access to all of your fb data, and other ridiculous abilities like to be able to post to your wall, just ruined facebook login for me. These days when I see an app offering the ability to login via FB I just assume they're going to try to overreach when it comes to my data/profile and I just move on.

Every time a site asks me to login with FB, their requested permissions include access to my friends list, my personal info, etc. -- a deal breaker. All I want is to not have to make yet another password and to have a "one-click" login experience, I don't want to share all my data too.

Me too, I accept only Google for my personnal identity. Sometime Linkedin or Github when that make sense and there are more features as importing your contacts/repos for more networkingcollaboration etc... Facebook and Twitter is a big NO everytime.
