Because that is piece-by-piece sign, and it is something you want to avoid when your entire process is based around a long iterative process. They worked for a year on it, with the idea this will support what they are going to do next. They need a LOT of reason to backpeddle. And apart from, what, ten dudes complaining a lot, the rest of social media around ED is busy hyping DW2 etc. Now, if that flops and noone participates, THAT will be an obvious sign to FD. But if DW2 is a great success, player counts are high, positive news everywhere except in one or two topics here: they wont change.
Oh yeah. People who like the FSS arent real explorers but bubble dwellers who only care for credits etc etc. The whole 'no real explorer' is funny because it is as close to a literal textbook example of a fallacy as you can get, so I always assume it is used in jest. After all, none of us are space explorers, we're all grown dudes fiddling with our stick in the dark preferring silly version A or B of 'space exploration' while we make spaceship noises. Maybe it helps I am 'combat explorer', so I've had the same 'no real combat pilot' discussion before.
Now, being a person who prefers fixed weapons and the FSS, obviously I am the real combat pilot and space explorer, so there.
