Something something reaping what you sow, etc...
Many are bringing up other games such as Watch Dogs into the mix. The important difference between WD and NMS is that the only time where WD ever seemed graphically (superficially) misrepresented was in its original reveal video, more than a year before release. Promotion material around the launch of the game faithfully represented the game we actually got.
In the case of No Man's Sky, the promotion material around the time of release, and even after release, did not and does not represent the game. Not only graphically, but in core gameplay features. This isn't just a superficial graphical downgrade that doesn't factor much into the actual enjoyment and value of the game. It's the actual GAME portion of the game that's completely and grossly misrepresented, even to this day.
