I agree but one would expect that AV vendors have enough opportunities to make money without sacrificing their users and their reputation. Look at how many products AVG has. I think they should do just fine by converting free users to paid subscriptions. Couple of years ago most of their revenue came from toolbars. Since then they have converted their business model to push more for premium upsell. They do it well, I don't have problem with such a business model. Free users serve them well as free marketing force, they don't have to abuse them.
