It depends on which kids, and how they're interacting online.
For example, for adults that don't get it, Fortnite seems like a game where the objective is to shoot strangers. But if you look closer, you'll see that Fortnite is a big chat room where friends meet, and the contrived activity that brings them together is the game.
It's similar to an arcade in the '80s. Some kids went to beat the donkey Kong record, but most kids went there to hang out with their friends.
