> If you're really anti ads, don't take the content for free, find another piece of content that answers your ad-free philosophy. Google is in the process of breaking this deal themselves - they're now adding ads to videos which users did not opt to monetize, and they're keeping 100% of the revenue. Taking the content for free, if you will.
They, at least, offer a free hosting service. Not ideal to monetize on the back of the creator's work, but it's not comparable with friendly piracy rationalised through semantics behind what User Agent means (as per parent comment).
Remember, forcing you to watch ads means it's not free - it's you trading irreplaceable moments of your life for something. Unless your time is worth absolutely nothing, ads are extremely expensive to you.
