Well, I guess you're right. But the content was developed and cut off the original game for the sake of profit.

It wasn't for the sake of profit. Activision essentially held Bungie by the balls and forced them to completely overhaul Destiny and start from scratch a year before release. Activision then pushed Bungie to release the game on time as stated in their contract, so a game in shambles came out. Bungie, fortunately for us, managed to leave nearly all of the games lore, original design and story telling in tact, but they basically had to do it in the form of Grimoire Cards. It is unfortunate they are not viewable in the game. Destiny was contracted to have at least 3 expansions per game for the span of 10 years, so that part had never changed.
