From YouTube’s Weblog:
Specifically, content that falsely alleges that approved vaccines are dangerous and cause chronic health effects, claims that vaccines do not reduce transmission or contraction of disease, or contains misinformation on the substances contained in vaccines will be removed. This would include content that falsely says that approved vaccines cause autism, cancer or infertility, or that substances in vaccines can track those who receive them. Our policies not only cover specific routine immunizations like for measles or Hepatitis B, but also apply to general statements about vaccines.
There are some exemptions — you can share personal anecdotes, for example, which is good. But I don’t see how this will do anything other than further entrench groups into their existing ideology. The people that are in favor of vaccines will see a higher concentration of content that affirms their view and those that oppose them will point to the policy as an example of censoring what they consider to be the truth.
I’m of the opinion that more dialog is always better than less.
