I use uBlock as well, It does not block the ads from youtube. However, that said, I'm willing to allow for some advertising. The content creators do need to make some form of income. Completely blocking all ad revenue means they have less incentive to provide new content. I just hate the pop-ups and pop-unders and most auto-play type advertising (like those high-lighted words that pop up a commercial). If I could get around those, I'd be happy with banners.
