I would say it's better this way for society as a whole. A splintered populace is harder to control. And I'm not just talking about some "guv'ment out to get us" thing, because they're trying to kill encryption and other dumb stuff like that already. But it's a lot harder for other people to spread misinformation if the majority of the population isn't centered around 3 websites.

Of course, there are negatives to this whole thing, too. But I think the net positive will be greater.
