It feels to me like both sides in this debate want to argue "of course it's patently obvious that I'm right". But services like YouTube and Facebook have no real historical precedents in terms of audience reach, and it's hard to think of a more rock-and-a-hard-place situation than choosing between "force a private company to treat their property like a public square no matter the cost to society" and "allow a private company to dictate what's allowed in a de facto public square."

So, yes, of course it's possible a gatekeeper would find it easier to misinform the populace. Over the long term, it's almost guaranteed. Yet it's also possible -- in fact, one can argue the probability is essentially 1.0 -- that refusing to have any gates will also misinform the populace. If we're looking for a blanket rule that will cover all possible situations in this new information reality, we're probably looking in vain.
