It sounds like he really wanted to work at Bungie, but since 343 makes Halo games now his only option is to work at 343, who he trashed online in the past (like a lot of Bungie fanboys did after 343 took the reins). At which point I just suggest that he apply to work at Bungie instead. I get it, Destiny isn't Halo,, but he seemed a bit selfish in his criticism of 343 ("no one deserves their job", then he gets a job there, it creates an air of superiority that he could do others' job better, which is terrible for team synergy), and I think he would find some solace in Bungie's tools.
This blowing up is only going to hurt him, though, as prospective employers could become aware that this guy potentially uses an anonymous handle to bag on coworkers and peers in the industry. Best of luck to the guy if he really does have the talent to back it up, but you reap what you sow when you shitpost online with the same handle year-after-year.
One day people might start realizing that what they say on the internet actually means something sometimes.
I wonder this whenever I see people in Facebook-powered comment sections spewing hateful vitriol with their actual name and the place they work at tagged next to their name. Eventually you have to draw a line on being an asshat online.
