Why would it be to late for that statment? SE is giving us the tools for player interaction, wether you make use of this tools or not is up to you. They're giving you the means to form "relationships" with other people, they dont have to give you the people for that too.
Do you expect your goverment to find you a wife/husband because they're providing a marriage service too?
There ARE means in this game to find like minded players - PF, the forums, maybe. Why would SE be required to help you find a friend?
And I frankly dont understand why you assume I'm cold hearted just because I dont think a game company should be running a dating services for all those lonely souls out there when they're main focus is, well, you guess: a video game that might include player interaction but doesnt require you to play it with your bff or partner for life.
(I also dont see neither the mentor nor the FC-system being upgraded - housing-system? I suppose you're talking about sharing your house with friends? Ofc people want to play with their friends and its good that SE is giving us the tools for that. They dont have to give us friends though.)
