In many cases they are. We offer a few free WordPress plugins that get us some very interesting emails. You'd really be surprised at the level of entitlement some people have when you offer something for free. On the other hand, paying clients really respect their time and our time. I'm not saying it's all their fault. It's your responsibility (as someone who chooses freemium as a business model) to make sure you don't allow them to be jerks to you. That means putting limits on how much resources you allocate to supporting them and having clear revenue channels that allow you to make your revenue goals. Still, many freeloaders can be plain jerks at times.
