paladin181: Just like with Television stations in the US though, certain regulations need to be put in place once a platform reaches a certain ubiquity. I'm all about private entities and their rights, but once a private entity becomes the de facto communication of its type, it needs to have protections for its users to keep censorship from happening. Free speech in a private venue is not exactly protected. But when that private venue is essentially a public street (and reaches far more than any one public street) then the owner should not be allowed to remove speech.
Whilst I agree with your point of regulating mass media, I don't think they should be regulated to avoid censorship but to hold them accountable for the information which flows through their channels.
I know my opinion on the matter ins't a popular one but considering Youtube's algorithm favours outrage, controversies, viral videos, daily uploads, lengthy uploads, response videos amongst popular channels, etc. I think Youtube needs to censor itself, especially since they have such a massive potential influence over democratic processes no matter which side we're talking about. Youtube needs censorship because Youtube is designed to hook viewers up with an iron grip and that is much easily accomplished with emotion than with erudition. Youtube moneymakers know this and they shape their information accordingly, lest we forget the title of the video posted by the OP, "Google's Censorious Urges are Playing a VERY DANGEROUS Game" which is clickbaity and tendentious but it's great for views count standards.
Google, Facebook, etc. can't and should not allow everything on their platform, not because they're private ventures and can do with their platforms whatever they please, but because their immediacy, scale, popularity and design can be devastating if allowed to host and indirectly or directly promote certain types of harmful content. I know this one will come harshly but remember the Rwandan genocide? A local radio station played a major role on the massacre. Imagine what could happen today if globalised mass media platforms were not scrutinised and censored to a degree, what could happen if those 'digital streets' which are full and thrive on stupidity and ignorance (tide pod challenge anyone?) were let loose. The fact is that comparing them to a street is a false equivalence because on the streets there isn't the same degree of anonymity and there's also patrolling police, people on the street act more rationally and what they say has a limited reach.
Let's not kid ourselves, more often than not the debate on 'freedom of speech' is a euphemism for manipulation and control, not a quest for enlightenment.
