'Need' is tricky to define in this case. Many 'freemium' games are very different experiences based on whether or not you pay via additional IAP. From what I gather, not having actually played it, Dungeon Keeper is about the most extreme example of this. It sounds like you really do need to pay in order to play the actual game , as opposed to playing something which many would describe as not really being the game .
Do you really want EU bureaucrats examining each game and deciding how playable it is with or without certain item? If the game is that bad - uninstall it, write one-star review for it and be done with it.
Sure we all know the type of game this is targeted at. The time-sink freemium farmville clone that makes it just a little too easy to buy those gems/coins/cash/whatever that makes the timer tick down faster.
What if the IAP in my game is just to remove ads? What if it's solely cosmetic?
Governments do not have the best track record when it comes to comprehension of nuance and basic reality.
I'd like to think that a person is smart enough to tell when their OS pops up the payment dialog that they are under no obligation to click "yes".
