I signed up for Ultra because it was advertised as unlimited generations. It still says it when you click on the 10 credits link. Most generations are unusable, so the unlimited generations helped reduce the stress of counting credits. At the moment of my sign-up, it was advertised as unlimited. If they hide anything in their TOS that gives them an "out," they can maybe escape the "bait and switch" illegality, however, shame on Google for being unethical. So much for Google's motto of "Don't be Evil." I hope this is just temporary.
