I'm not sure why you keep not understanding, despite simple words in a language you clearly speak. I don't support youtube, I don't not support youtube. Youtube can do whatever the hell they want, and I'll do the same. The reason youtube doesn't block my adblocker for example, is because it doesn't know I'm using one. It still downloads all their ads, and google has no way to know if my browser doesn't actually display them on my monitor or send them to my speakers, because a website doesn't have the access to my browser needed to see that - it runs in a little tabbed sandbox separate from the renderer process.

Are you typing up an email right now? I can't tell, I'm on HN on my computer. To be able to tell what you're doing, I'd need to be on your computer. Hope that helps explain things.
