It's a flawed argument.
2/ some are not (netflix) and are still profitable Conclusion/ Every thing should be not free. It make no logical sense. But obviously the dude has an agenda. Why some may afford to be paid service why other cannot.
Facebook, Twiter, googl, reddit, all can only survive if people create content for them (a Facebook post, a twit, a search request and subsequent link selection).
The second they charge 1 cent they're dead. Even without charging they risk to be killed anytime (as Myspace taught us) if people start to massively switch to other platform.

1/ major internet player (Facebook,Googl) are free
