Every game is the same, you buy a license play it, the content creator has all of the power in deciding what you can and can not do or have access to while playing the game. The best you can do if you feel ripped off / cheated is vote with your wallet and not buy anything from them. As I already stated, I'm not in that boat, I enjoy playing Destiny and to me buying a new expansion every few months is totally worth it to keep playing. I don't play any other games so depending on the cost of the DLC I'm basically buying a new game (or in the case of $20 DLCs a used game) every 4 months.
