People actually think there isn't even a 1% chance this was an unfortunate coincidence? The brain seeks patterns, and if you're familiar with something you'll often see it in places it doesn't actually exist. Just a vague set of iconography that you connect together to see something you feel you see. The colours are the same! There's a letter that is the same! There is the use of a line! I admit I can see how people are seeing it, but without the flag image next to it and people pointing out what bit is what... Yeah.
I mean, can anyone remember "Jesus toast" from the early internet days? Sure, someone's toaster made a bit of toast that vaguely looked like it had Jesus on it and it goes viral or sells on eBay. The brain and eyes do most of the magic connecting dots with imagery. People see things in the clouds, in water, on roadside brick patterns, etc.
It's being removed anyway as far as I can tell. The 100% certainty Bungie were invaded by a designer that is 100% guilty of hate crime and needs fired asap is just a bit over the top. It's patched out, and Bungie can ask around internally, but don't be surprised if it was a coincidence.
