To say that you don't get any profit or only a ver small profit from the free accounts is like saying the Pokémon Company gets no money from the people that play Pokemon Go without paying. The fact that BGA is always full of people willing to play lots of different games even if they can't/don't want to pay is a huge part of its success, I've had a free account for years, and yet I've played and brought friends who eventually bought a premium account, all because I, a free user, have played and loved the site.
I don't like the decision you made in general, but that's for you to decide as a company, but to say you get nothing or almost nothing out of your free games is just deceiving yourselves.
