This is the explanation he posted online:

This is a little embarrassing and I’ve struggled back and forth about posting this publicly but I think it’s best if I explain this once to everyone, and not a hundred times individually. As of yesterday 343 revoked their offer to me as a level designer. It seems that they weren’t pleased with the way I’ve criticized them in the past between my posts on Forgehub and Beyond. So whoever made the anonymous account on r/halo and posted screenshots of old posts, well…congrats! You won.

In fact you won to the extent so that I already quit my prior job, sold my place in California, placed a $2500 payment on an apartment in Bellevue Washington (among other expenses), and began transporting my belongings up there. Only to find out from the agency I was working under that my offer was withdrawn. Which puts me in a tricky position where I am both unemployed (no Treyarch or 343) and scrambling to find some place to live – as I had briefly moved my belongings to my parents during this weird transition phase. So life has definitely thrown me a curve ball here.

Now hear me, I’m not looking for pity. I believe I’m currently reaping what I’ve sowed; and it’s not that I regret criticizing 343 publicly in the past because they are not above reproach – they know this as well. But rather the way I’ve gone about it could always have been more…professional. At least considering that my goal has always been to be in the industry I should’ve held myself to a higher standard (if that’s not your goal then flame on). I suppose a little patience over the years could have gone a long way in this moment. I just wish communication would have been a bit clearer going either way to have avoided the pickle I’m currently in.

The expenses aren’t the bad part; I can deal with that. I have no doubt I can find another level design job in the industry given time. The aspect of this that really drives home is that this was Halo. After all these years of forging, I thought what I wanted was 1: a proper editor without boundaries, 2:to be a professional. It wasn’t until I was sitting at Treyarch working on the highest grossing video game franchise in the world with every ounce of dev power at my disposal did I realize that it wasn’t about the editor, or the money, or the prestige. In fact after a 12 hour work day at Treyarch I would commute 3 hours home, sit down in front of my xbox, and start forging.

And I think it was in that moment that everything really clicked – nothing really matters unless you’re building for the game you love. And for as long as I can remember it’s been Halo, it’s always been Halo. All the dev tools in the world couldn’t drive me away from clunking blocks together in forge just to have a single good 2v2 match before I knocked out for the night. People always ask me why I play so much Halo 5 (Level 142) if all I do is bitch about it. Well, I’d rather play a Halo game I hate than the greatest Battlefield game out there. Or the best Call of Duty. Or the best such and such. Even with all the frivolous mechanics that have entered the franchise in the past decade that I don’t agree with, the simple ebb and flow of a good pistol battle is something that you’re not going to find elsewhere.

I was excited to leave my cushy Southern California to go to rainy Washington, I was excited to take a ~$10,000 paycut. I was excited because I had finally made it to the place I felt like I was born to be in; Halo. And honestly that’s all that mattered to me – working on the franchise that I loved. So to essentially already be in the door and then pushed back out is….difficult.

And even more difficult knowing that this is essentially a forever no, a “you insulted our franchise and employees and will probably never get a chance to work here” no. It’s disheartening to the point where I’m not even sure if I want to pursue another position in the game industry at this point. In the back of my head no matter where I worked I always knew I wanted to end at Halo. That’s what I love, that’s where my strongest talents lie, and that’s what I know. So to have the reality spelled out for me where that position will likely never happen is a hard pill to swallow right now.

The few conversations I had with Tom French were delightful. The man was incredibly friendly, welcoming, understanding. I have no doubt that he would be a pleasure to work with and a great man to work under. But I just wanted to let you guys know that I’m sorry this didn’t end up playing out. I was as excited as any of you were to contribute to the franchise and hopefully really design maps that would stand the test of time, I wanted to really make this franchise the juggernaut we all know it can be. So, sorry to let everyone down. This one was on me.

EDIT: I’m seeing a lot of posts over a lot of mediums (holy shit) that are pointing to my past post history. I just want to reiterate:

It would not be hard to find comments deemed unacceptable through my post history on any forum. I am aware of this, as I’ve been more than blunt in the past. Many of these comments made out of anger, and many as drive-by comments with no context other than my poor attitude. I’ve never denied this, and I don’t blame them for making the decision they did. It’s understandable.

I also don’t believe my forum persona reflects my actual personality and ability to work in teams. Yes this is a bummer but I could hardly expect anyone making the hiring decision to base me off of anything except what I’ve given them to see me by. This is the persona they know because I provided it to them. Man makes dumb comments online, man loses job. Tale as old as time. What’s new.

Sad story. I guess if you want some moral: be polite and watch what you say online. Remember, Internet never forgets.
