Right, I read it as your videos cannot be shown on the ad free site, since they wont be ad free. They should still show on the regular YouTube page.

Edit: Apparently I was wrong. There is another article on the front page stating they will be hidden on all forms of YouTube.

So in practice this means that if you pay for the subscription you get access to less content.

Looks like they are actually strong arming everyone into allowing the ad free version so this outcome does not happen...I understand their reasoning, but is also pretty hostile at the same time. I would definitely allow it, and can't think of a good reason not to, but not giving people a real choice could be a problem.

No, it means that to avoid the situation you just subscribed YouTube forced everyone to agree to be on the subscription plan or they'd effectively be kicked off of YouTube

If I were a content producer, I don't think I'd like that policy, but as a consumer, it makes the service more usable, since I know that anything I can see on the ad-supported Youtube site would be available on the paid site.

Much better than the model that cable TV uses where when I look at the channel guide I can see all of the channels, including the ones that I haven't subscribed to, and it's not until I try to watch a show on one of them that I discover that I can't see it.

If that's what happened then good, but it sounds like people who don't agree aren't getting kicked off youtube, they're just not shown to subscribers.

Yeah that is a pretty odd outcome.

If they agreed to share ad revenue, continue to share ad revenue. Subscribers don't see ads, so no ad revenue to share. Sign up to share subscription revenue at your convenience.
