read the comments below the video.
There can be many reasons why people and corporations want to control information of course.
And now there is probably more money and power at stake than ever before.
Just imagine what would happen if people become sick from the injections and furious citizens start accusing the establishment for trying to kill them.
That would change everything so i bet there are many who wants to prevent people from becoming aware of such information.
