I too bought in a life time pass, I've been following the game via forum and youtube reactions since the alpha.
And it's always been sold as the basic concept at launch, (the empty house analogy).
If you can point to a solid, Frontier Development List/newsletters of the expected release features of the game and a cross comparison to actual released games that everyone keeps alluding too???
because here is where it gets murky.
ED may of sold the game as "team up with your mates", and going of a global voice comes to your mates, and a private session -> they have accomplished this.
But not to the degree the Wings update will give you.....but then how did majority of wings come about, part kickstarter plan part Beta feedback? Suddenly the lines start blurring, correct?
So again, you need to pull out this magical cross referenced feature list that Frontier provided to the worlds press of what the game was supposed to be like on release, not the kick-starter list where it's a mix of discussion of all future versions are accounted for as a final product (and I shall even be bold to mention the offline version of the game).
highlighting a developer post on the forums from years ago doesn't count as an intended feature list either, because those were speculative posts, fishing for comments and feeback.
My reasoning is because of the following examples.
Combat logging for example is an issue and they got a forum post from 2013 to plans of how to handle it.
I've started my own post about "repairing the ship", only to get a link from the forum in years ago of how they like to handle it.
Because, sure they got PLANS,
but of course until ship-boarding and EVA are added, there is little point to execute the parts of the game that would power down your ship enough to force you to leave your cockpit to recreate parts of the Abyss/Wrath of Kahn were you A-team style patch up your vessel....so instead we just explode.
Similarly I saw a dev reply about someone claiming mining being unbalanced/broken, and the reply was something along the lines of it's more balanced when planetary mining is to be incorporated.
So even something feeling nerfed/borked right now, (or as some dramatically call it, "broken") may even have a pre-nerfed to account for a planned update. (we don't have their magic ball / roadmap to be sure).
Plans change and they have changed specifically due to player feedback (super-cruise, GUI etc etc). Those changes alter the road-map and mile-stones, but big things like a christmas release will still go ahead as the game was cleared for maximum profit at Christmas to help fund more development, not to mention, they ordered in the amazon servers months in advance, and you best start bloody well using them once you start paying for them, correct? Whether your game is ready or not, otherwise you are just urinating backers money into the wind.....am I right?
I think what I'm getting at, is that the game may have physically been shipped out in a hurry, but what didn't get rushed out where incomplete and full set of entirely buggy features.
You see that's a positive thing (features didn't get rushed out), and instead the team are taking their time to get stuff right and implement the in due time.
That last sentence though is pure conjecture because just like there was never a laid out release feature set, there isn't one now either. Its basically pay me now ill do the work later. You don't know if they are trying to get it right or cramming it out the door to move on.
