Is urgency really a dark pattern? To me it seems like basic sales and is present on everything from TV infomercials (buy now, limited stocks, only for the next 15 minutes + operators standing by) to brick and mortar sales that only last until the end of the week. Granted, it's a different version of urgency and the other stuff looks shady, but urgency isn't something I'd automatically put in the 'dark pattern' box.
