You might be right that Blizzard game don't make as much pure profit. However, COD and Madden are prime examples of the bastardization of the video games industry, where companies are putting profits far ahead of making actual enjoyable games. Kotick is a pioneer in this respect, being the best in the biz at making games unfun reskinned garbage and making a mint while doing it.

IMO keeping someone like Kotick around for his money making prowess is extremely short sighted. One of these days people are going to pick up on the ruse. You can already see it with Blizzard's waning fanbase for games like Overwatch and WoW.
