Who said Wagner lost 80% of manpower?

So, yesterday YouTube deleted the video below and gave my account a strike. In the video, Evgeniy Prigozhin, the CEO of Wagner, calls on Zelensky to allow Ukrainian fighters to leave the besieged city of Bakhmut.

I understand Prigozhin has been labeled a terrorist by Washington, and Brussels and all the bonafide, handshake worthy individuals. Still, I do not understand the problem fucking YouTube has with this video. This is nothing but censorship to protect the Zelensky regime.

The battle of Bakhmut was raging since summer and Ukraine sent its most capable units to prevent Russia from encircling the city and creating a hot pot.
