From my perspective You were the victim of a witch-hunt on a slow news day. Followed by a focused campaign against Mozilla by a dedicated group of troll-activists who knew where to put the most pressure via third parties. They knew how to make themselves appear larger than they really were.
It's happened a few times since then but none were as successful as the attack on you. (Dropbox, Donglegate, Crockford, Palmer Luckey etc.)
The troll's success with Mozilla has led them to attack other open source projects as well with small, loud mobs shaking down various projects on GitHub for fealty through codes of conduct and inane commits removing or editing things they perceive as offensive.
I really dislike this trend in the tech industry. Software ought to be apolitical. There shouldn't be a conservative browser and a liberal one. Being a libertarian leaning conservative I run up against this kind of left wing xenophobia all the time. I worry it's only a matter of time before it happens to me as well.
I hope this hasn't destroyed your career prospects for the future. Have you had trouble finding work since the incident?
By the way I'm sorry for initially saying you were fired from Mozilla. A more nuanced description was warranted.
