No, they dont make money becuase people are lazy, they make molney by offering things ppeople want.
No, they make money by people inputting information on themselves and the advertising towards that information.
You could argue that by that information, they do offer people what they want (in advertising deals etc.) but it's still what it is.
As to the OPs point I'll use a delightful quote from magnolia.

The problem is that most people are self-absorbed cretins with a hilariously misguided belief that other people (who are also self-absorbed cretins) have any interest in their meaningless lives other than to quietly judge them for being self-absorbed cretins.
The internet in general and facebook in particular remind us on a daily basis that the majority of people are stupid, vain, vapid, vacuous toddlers with little self-control in how they portray themselves, how they talk to others, and how they interact with the world. We live in a world where selfies project your brand even if that brand is utterly awful and pointless.
If you're not giving facebook information, you don't exist to them and the others that need your input to be self obsessed with themselves and in turn yourself.
It's not that the rumour of being dead is greater or that you don't exist, you're just not a person that needs an ego stroke from someone so remote you might not know or even met in a physical presence.
The person you knew physically in the past doesn't need to be
"liked" in the present and doesn't have the need to interact with people that do. They haven't put there identity on there as they don't want to be seen as someone that needs re-assurance from other identities. Not that they don't want to be seen at all.
