Here's the thing - in a game like this, any discovery can only be made once before the entire player base finds out the answer through other means (ie out-of-game communication). It doesn't make sense for it to be easy at all, but it shouldn't be impossible either; there's something out there, in the midst of 400 billion stars. FD want us to find it, but it shouldn't be too easy because it's not one of those games.
It's pretty obvious that they've got an overall story to tell, but I do sort of wonder how much of the timeline of the story is determined by the player base; if we do crack it ahead of schedule, will they accelerate the story to account for it? It's almost certain that the opposite is true (if we prove ourselves to be properly inept to the point that they have to put a big flashing arrow next to the answer).
Anyway...they'd be mad to stifle this kind of community activity. Even if this is a wild goose chase (and the overwhelming evidence is to the contrary, in my opinion), they should be taking notice and actually making puzzles like this for the future. After all, not all of us enjoy the game for the same reasons. Not only that...the 37,000-odd views of my Unknown Artefact video on YouTube in 36 hours would tend to suggest that there are far more people interested in this than just the ones who're contributing to the threads on here.
