It is not that simple though, it is not one line of code. It's a balance between players with and without the dark below. There is debugging and play testing to make sure there are no loop holes in the system. There is an issue of setting up a new match making system in regards to the crucible because of the now smaller player pool. What you are asking for is a bunch of work and a ton of money to be directed at people who are no longer supporting the project. There is never "just one line of code." There are consequences to every action and oppurtunity cost to said actions. Bungie chose to support continually paying customers instead of catering to people who are stagnant in the game. I for one support choosing progress.

Ok, say I buy a Harmon GPS device and they suddenly stop GPS service on it? Kind of the same thing.

It's not because most gps come with pre installed maps that require you to get a new one every 5 years-ish. You're right that they don't remove features but they also aren't connected to the internet. It would be comparing Destiny to an old snes game. Sure you can still play those games, but they aren't being updated in real time. An online game is significantly different from old video games or GPS for that matter. Apple's to online oranges really. And it's kind of bad analogy because gps and video games are very loosely connect. Gps only perform one function and never update. If you were talking about gps apps in your phone, they are paid through other means and therefore aren't connected to video games at all because Destiny is the product and not a platform to advertise on. Also, Harmon could stop giving service on your GPS at anytime because you bought the hardware, not the satlite network to run it. I don't know why they would, but they could.

You don't think there would be a similar uproar if Garmin stopped providing the satellite service to a GPS unit three months after it was purchased without warning the customer that that would happen?

There would be an uproar. It it doesn't mean they aren't in the right. Also, satilite privligaes are expsensives. If they go under or decide that they aren't making enough money to use them, should they be obligated to maintain a satlite connection to their units at further cost? And again, this situation is nothing like if Garmin took down the satalites because if gps lost signal than you lose all access. You still have access to all activities, just not with the same freedom.

Here's this semantics argument again. We do not have access to the same activities no matter how you word it. What if I bought HoW specifically for the high level strike playlist? Now I can't do it anymore. Yes the content is there but it's not really the same. I'm sure you'll find fault with this analogy as well, but it's like buying a sports car and the company releases new software for the on board computer as an upgrade, but I you don't buy it, they force an update that only allows your car 1/2 of the horsepower it's capable of. I am really not understanding why in the world anyone thinks what bungie did was right.
