Many, perhaps even most, will take advantage and consume/enjoy content without giving back, like you said you would selfishly do. But in the end that’s ok because there are enough people who aren’t selfish and who realize that life is not a free ride for anyone and they usually end up supporting more than they need to.

I support your view, that V4V is actually donating for something that was valuable for you. I think it is therefor powerful, since it is kind of a libre-opensource- philosophy. So everyone should be able to read the content for free. And those who have the money to support the creator, do so. Like this people from poor circumstances still get full access.
