Social engineering is more two sided. You are trying to get something out of these people, like something very concrete. This is more propaganda.

Those people generally don't put it on their resumes, having Facebook on your resume is now something that makes it end up in the trash.

Absolutely. There's a difference in scale and intent, however. Probably simplifying here...

I think the hacking thing always had a bit more of a Robin Hood complex coupled with it. The lone renegades taking on powers and organizations much larger than themselves for entertainment, or acquiring status that they weren't otherwise bestowed.

This is powers using it to manipulate other powers, where the price is paid by the people 'Robin Hoods' were never originally out to exploit.
