What? They probably wern't even in bed when you posted this!
So, he's got bored/fed up/whatever with ED. The guy has sunk thousands of hours into the game. We will all reach that stage sooner or later.
There are many reasons why FD might want to consider changing how they do things, and many reasons why they shouldn't. KB playing another game isn't one of those reasons. Hell, Obsidian Ant stopping playing wouldn't be a reason either. Or me stopping or you.
If a majority stopped playing... yeah, maybe. Or maybe FD would simply shut down the project and start a new one at that point. At the end of the day, that is what will happen eventually.
But only FD know the numbers of people playing.
On the flip side, we have new people joining the forums and playing the game every day: https://forums.frontier.co.uk/forumdisplay.php/16-Introductions
And that's just those who announce themselves.
Some of those in future might become content creators. Or maybe they will play 10, 100, 1000 hours and quit.
The idea is, that Frontier might want to take a keener interest in the narrative that surrounds the development of their IP. They seem to operate inside a bubble, either unaware or deliberately ignorant of the wider social discourse surrounding Elite. Whether that discourse is founded in fact is entirely irrelevant, eventually, the myths become reality once enough patrons or potential patrons believe it to be true.
