"Customer Relationship Management" got abbreviated many years ago, so now 'Social' comes along and gets bolted on - linguistically - as "Social CRM". And that linguistic "bolting-on" is reflected in the strategies being pushed by the big guns: it's CRM just as you've always known it, but with Social channels bolted-on.
Imagine if we had never abbreviated Customer Relationship Management. How would you read (aloud) "Social Customer Relationship Management"?
