Sounds more like extortion. EAC built this franchise from the ground up since 1993 and FIFA had nothing to do with it other than four letters.
FIFA in the game name give it “official” branding, which they would never have otherwise.
The main things FIFA brings to the table for EA is the name, and the World Cup competition. EA clearly things they aren't worth as much as FIFA wants for them, hence the current wrangling.
If the deals falls through then "EA Sports FC" (or whatver it ends up being called) will still have all the teams / leagues locked up. So a theoretical FIFA game from someone else would presumably still have the same disadvantages as Pro Evo etc.
