you seem to forghet that during original pledge campaign they clearly said this future contents would have been paid DLC.
Or maybe you know but like spreading some lies.
They did tho not as clearly as that.
They said they wanted to expand the game.
playable ships to the game.
The initial release of Elite: Dangerous doesn't mark the end of development. We intend to continue expanding the game both with new content and new features. A good example of this is planetary landings. We have an ambitious goal for landings to include new gameplay and a rich variety of worlds to explore. To achieve our goal we want the planets to come to life. We also want to add leaving the ships so you can explore space stations or board enemy vessels or even just to look around your own.
This is how they communicated those expansions would not be free.
The main reason for treating these as expansions is so we can approach these with the proper development resources that we require to do them well. We don't plan or desire to just tick a box, we want to make these additions something significant.
Extra resources here having the meaning of money, so those expansions are DLC's.
When you're reading that in 2013 or whenever it was the communication that each of these expanded features would come at an extra cost post launch is about as clear as mud, but it satisfies the lawyers.
