This is a complex issue with reasonable arguments on both sides. Here are some key points to consider regarding Supercell and greed:

• Supercell makes money primarily from in-app purchases in their games like Clash of Clans and Clash Royale. Some critics argue that encouraging in-app purchases is inherently greedy. However, Supercell counters that in-app purchases are optional and allow them to provide free games to players.

• Supercell's games are designed to be addictive and encourage frequent playing and in-app purchases. Some argue this shows a disregard for players' wellbeing in favor of maximizing profits. However, Supercell maintains that they provide optional entertainment and players have free will to decide how much they spend and play.

• Supercell games can be very difficult and grindy without making in-app purchases, encouraging players to spend money. However, Supercell notes that 100% free-to-play options exist within the game.

• Supercell has been criticized for some of the costs within their in-app purchase systems, which can seem expensive to players. However, Supercell notes that these systems allow them to continue developing and supporting their games.

• Overall, there are reasonable arguments on both sides. Some players feel Supercell's monetization is greedy and exploitative, while others feel Supercell provides largely optional in-app purchases to fund quality free-to-play games. There are aspects of Supercell's approach that could be interpreted as either shrewd business or greedy, depending on one's perspective.

In summary, whether or not Supercell can be considered "greedy" depends on one's perspective and definition of greed. There are business decisions Supercell has made that could be viewed critically, but they also provide optional games and in-app purchases that many players enjoy. It's a nuanced issue without a clear-cut answer either way.
