The weekly strikes and IB were things that came with the base game, and continued to work without any DLC until TTK came out. Advertised or not they were still apart of my original 60$ purchase. With them gone now for those who don't have the dlc, it is the same as taking content away. It only provides evidence to my theory that bungie us trying downgrade you're experience without TTK to convince those who don't have it to buy it.
