My company forced us to use only Chrome on our PC's and one of the things I was worried about was the ads. I put youtube in the background while I work.
And I was surprised by how...... My experience was exactly the same as Firefox and Brave. Ok, actually, one or two ads managed to slip through and appeared in the front page - albeit rarely and randomly - but I never got those ads at the beginning of the video. On other websites, I never got ads.
I was wondering, then, if there was some catch. Maybe the trackers would still get through or something. But according to that link, not even that? lol
