An apartment (at least in the US) is well understood to be a yearly lease. Software purchasing not. Similar software may be priced monthly, annually, everything upfront, or even free. If you put a price and list it as monthly and neglect to mention anywhere that it requires a year agreement, then it's an obvious dark pattern. You know it is because they easily could add "annual contract required" underneath, like most others do when they show annual pricing as a monthly rate (IME).
