Should Youtube remove conspiracy theory videos? 9/11, Sandyhook, Vaxing, etc?

I really enjoy a good conspiracy video, and often, they do present things that can open your mind to things.

Now they seem to be all gone.

I know youtube said they were removing Sandyhook because people were contacting the parents of the victims and calling them liars, so they said that victims shouldn't be harrassed, etc.

But why remove 9/11 videos?

Or the Joe Biden touching girls inappropriately and moving into their personal space?

There should be a place on the web where freedom of speech exists and freedom of information.
