It's what they knew Joshua by playing Destiny, so why not commemorate him in such a way? I feel it helps bring to light that people(no matter how much "fun" they're having) are going through their own struggles, and if you've made good enough friends through a game such as Destiny, maybe it'll open up to some people being able to talk about things like what Joshua was going through. It doesn't hurt to at least try. But nah, let's come in here with negativity and just drive the nail in the coffin that no matter what, there'll be assholes in every place. Even somewhat of an obituary post made by some friends who probably were sharing awareness and laying to rest their Guardian friend they met when Destiny first opened up.
