And you are incorrect.
1. YouTube is not preventing you from posting the content.
2. YouTube has decided that it doesn't want to pay you for your content and is not running ads on your content.
YouTube is still subsidizing your content they are paying the cost of hosting it and bandwidth.
Are you prevented from speaking? No. Then it is not censorship.
Do you have a right to get paid for your content? Yes you do so do not put it on YouTube if you do not want them give it away.
Do you have a right to force YouTube to run ads on your content? No.
What you are doing is trying to use the ideas of "freedom of speech" and "rights" when it is really just a matter of money. AKA wrapping yourself in the flag.
Go to Vimeo or host the content on your own website. You no more have a right to demand that YouTube run ads on your content then you have a right to force NBC to run your show.
