No one does it because it's not polished or flushed out in a gameplay-loop sence. Players who play this for more than 100 hours dont care about credits.
We want good experiences.
Piracy is an incomplete gameplay, needing a very specific build, NPC's and players only flee, there is no negotiation gameplay. And it's very hard for non-engineered ships to even hatchbreak and steal a few commodities.
Horizons combat has some very dumb AI doing very basic combat. On barren non evolving cenarios where only more enemies spawn without progression.
Signal sources are diffrent skins for the same: drop somewhere and find redundant loot gameplay.
The same can be said for most activities. They are just there, not really developed into an fully engaging and polished experience.
Programming wise, they are just random cenarious triggered by BGS that spawn basic interactions that are up to the player to make interesting.
For years I say that the main problem with this game is GAMEPLAY LOOPS not being full on designed, or polished.
New features or content keeps on being introduced without addressing old problems like balancing, loops, objectives, relationship among activities.
I like ED alot, but it looks like a project for simulation alot of times, and not a game.
This behaviour is a big flaw of game design.
Look at any other sandbox game. Those that are considered good, are not good because the sand box is very big with a lot of sand.
Its the ones that have good sand castles and holes for the player to explore. Doesnt matter how far the edges of the box are, but how the sand is distributed inside of it.
And if the problem is money, than it's time to re-think its capitalization methods on a way that does not affect current promises.
I really like the Ideas bihind the update, but it just adds more sand to the box.
I've said this in 2015. The activities needed to be much more complex, not difficult but complex. It took years to FD to add exploration and mining to a minimum gameplay standard.
The core activities are very simple and the gameplay loop is VERY short.
