To quote the email from Hulu that recently dropped into my inbox:
> We are clarifying that, as we continue to increase the breadth and depth of the content we make available to you, circumstances may require that certain titles and types of content include ads, even in our 'no ads' or 'ad free' subscription tiers.
So at this point they aren't even bothering to rename the tier from "ad free" even as they put ads in it. Or maybe it's supposed to mean "the ads come free with it" now? Newspeak indeed.
