If I purchased a car with all the "bells and whistles", and in order to keep them active I had to buy another car, what then? I take it you think it's sound business to cut off a vast majority of content for people who have already spent $100+ on the Destiny and it's first two "DLCs"? If you purchased HoW you were purchasing ToO, but if you don't have TTK, you're cut out from an element of the advertised game you paid money to take part in (this also includes Strikes, etc.). Defending that kind of practice is asinine. It's you job as a consumer to rear in a company you support when they overstep the bounds of business and into sheer greed and distasteful acts. If you think it isn't, then go kick rocks.
