Personally I disagree that Youtube is only for fun and games; it's the primary news source for many people. I think it really comes down to this: when it comes to news and 'event analysis', Youtube only recommends controlled/shill channels. If you get sucked in to mainly watching a shill, as I did for a couple years with Alex Jones and his associates, you're by and large only going to be exposed to other shills. So it can take time to get exposure to genuine channels, if it ever happens. I think the mistake being made here is to assume the best of Google and Youtube when they have repeatedly proven themselves to be the worst: while they like Facebook are an easy and seemingly convenient place to post content, they like Facebook are controlled propaganda sources and part of the establishment, ultimately one and the same with the NSA and intelligence community i.e. 'media-intel-banking complex' i.e. shadow government. (They're far more objective on non-controversial content, which gives the false impression of universal objectivity). To say the least I think it's inadvisable to count on them to allow, let alone promote, the broad dissemination of content that they may perceive to be directly against their interests.
The only solution that does not involve putting all the control in the hands of the people you are speaking out against is to A) directly advertise content to viewers outside of controlled channels like Facebook, Google, and Youtube (i.e. on non/less-controlled search engines and social media platforms, or via word of mouth, flyers, bumper stickers, or other forms of street advertising (though even then they could just de-list/take down the video, shut down the channel, insert a 'glitch' into the link, audio/video playback, etc.) and/or B) host content independently, or on non/less-controlled platforms. Anything else and you risk being vulnerable to open/shadow censorship and blind to the number of actual views and reach of the content you are putting out. That's not to say the content shouldn't also be posted on controlled platforms like Facebook and Youtube (where the opportunity can be taken to promote the alternative/independent platform that is also hosting the content), just that one shouldn't count on non-censorship when doing so.
