The needs of the many outweigh the needs of the few.
A company makes decisions based on making the best possible experience for the majority of its customers, it does not ruin an experience or product for the sake of the few.
If it really were a majority, there wouldn't be over 5000 posts on this thread (roughly 50% for and 50% against)... the thread would be at most 10 pages long and everyone would be going "best idea ever", "+1". Since that's obviously not the case, you're by definition wrong on the internet.
In all seriousness, most of us want both modes, as promised.
- Offline for when we're in a casual mood, able to take a 20 minute quest, press "escape" to pause for an hour to watch a show or mow the lawns or have dinner or take a call or whatever, then come back to the desk, unpause and still have 20 minutes on our timer, instead of a bounty on our head and stolen goods in our cargo bay.
- Online for when we want that player interaction, have a bit of a dogfight, or go exploring with friends.
- Offline so I can play in my own sandbox, be the first person to explore those systems, have that sense of accomplishment without following in the footsteps of 100,000 other commanders who have more time to spend in game than I do.
- Online so I can be part of a community, participate in one of those wars that everyone speaks so highly of, take a side, fight with fellow commanders.
And that whole thing about "you couldn't have a rich single player universe" is wrong, simple solutions for some of those touted online-only features:
- You could have a war in a single player universe, if the player does enough missions for one faction or the other, it can be resolved in that faction's favor.
- You can do trading dynamics based on supply and demand and the AI haulers to provide that - the X3 series had pretty sophisticated markets/supply chain without the always-online requirement.
- You could have the NPCs follow in your footsteps as you explore, populating the system with new stations... something as simple as ejecting a beacon in orbit near an appropriate planet, then the NPCs could establish that new station and trade route over a series of hours/days/whatever was appropriate.
At the end of the day, we were promised both modes and we want both modes, and the safety net that offline mode gives us - so in 3-7 years time when the servers go offline, we can still play.
