Readers definitely still complain no matter how they're getting it. The difference is now their attitude is more justified since they actually put something into the product. Plus, if you're going to have to listen to whining either way it's obvious you should at least try to get something out of it yourself.
It is not only that, it is more about the value of something. People are more likely to place less value in something for free, versus something they paid for.
