Were you planning on paying for the content otherwise?
This becomes a problem for the publisher more so than the reader from my perspective. My job in the context of this relationship is fundamentally to consume your content. Your job is to figure out how to monetize your content in a way that isn't offensive and is sustainable.
I'm not saying I won't pay for quality content (I do!), but there needs to be a way to monetize that's respectful of your readers.
