What's really sad about this is the fact that the iOS's systems make it all too easy to circumvent all the timers. Here's a little handy secret that works for any freemium out there, from Candy Crush to this.
They all base their timers on your pad or smartphone's internal clock. You're stuck waiting four hours? Go in your device's settings and push the time ahead, after logging out. Log back in, and the game will be magically convinced that you've waited the required time. Thanks to this, you can expand fairly quickly at no cost towards yourself.
I discovered this after my folks bemoaned the waiting times on Candy Crush. Figured I'd poke around with the tablet's clock for the lulz and, well, whaddaya know - instant extra lives!
This doesn't make freemium models any better or easier to tolerate, but at least you can try and scam the scammers at their own game.
Once you're done playing, just reset your date and time to their proper settings, and you're good to go!
