Youtube Changing Video Comments Based On Whether You are Logged In Or Not

I might be naïve. But I just noticed something I have never noticed before. And that is that the comments under Youtube videos are different when I am signed into my Youtube account vs. when I am not. Super bizarre.

I was looking at this video when I noticed this:

When I am signed into my account, the comments sound a lot like what I think, which is that the virus is likely a very well-orchestrated psyop. But when I log out of my account, the comments change and they sound very mainstream and very angry about the video instead of supportive of it. It is beyond freaky.

Anyone else notice this? You might have to clear your history after you log out to see the changes. Not sure.
