Nope, you are wrong - in fact one very vocal KS backer stated that no one from 'those days' still plays
Seriously though, what you are describing is what FD released as part of their kickstarter campaign right - a list of thing they would like to do. Did they every state categorically that all those features would be in the game at release? I did a lot of large procurement activities when I was in the military (as in being part of Project Teams buying fleets of aircraft, talking Billions here, not Millions). One of the first things I was taught was the difference to a RFQ/RFT stating they shall do an activity and they would like to do an activity - the former can be held as a contractual element the latter can't. Basically too many people thought that the kickstart program was a legally binding entity instead of a request for donations.
I'm not talking about contracts nor kickstart nor contents available at release. I'm just talking about contents that people is waiting because they were announced (legally or not). So they are not coming from our own mind.
With X Rebirth they never talked about landing on planets in fact I've never expected that feature when I bought the game. Easy
