Additionally we found on our site that social login increased conversions for signups but those people are generally of lower value to our freemium product in the long run because they're less likely to want to pay.
In fact I "deleted" my Facebook existence and if you want to force me into a social login, any social login, you just lost me.
Your mileage may vary, of course.

And users who use social login will perhaps spend more time if it's not provided.
Any "friction", like having to enter a username, email and password is three more steps than a social login requires, costing these casual users.
So, I can believe it is highly effective for specific applications.

To be completely fair though, I never let anything login with my Facebook account, I just don't want other sites to have access to that data. And I would probably never use something like what this place provides, so people who use the net like me would never show up in their numbers.
In what way? It doesn't offer anything at all to counter that post, and doesn't in any way support the notion that users like social logins. It just shows that users who used social logins spent more time on the site.
