You make it sound like only Destiny is this way. Every game these days have dlc and microtransactions. It is the way of all business in the world... trying to take as much of your money as they can. But it is completely up to you how much they get. Don't be naive and think it will EVER go back. ALL game studios want your money first and foremost. They may change their tactics in the future but it will always be their main focus.
