He resigned - he was not terminated. He says so right on his personal blog:<p><a href="https://brendaneich.com/2014/04/the-next-mission/" rel="nofollow">https://brendaneich.com/2014/04/the-next-mission/</a><p>More details:

He was involved in Mozilla from the beginning. My gut tells me he did what he thought was right to allow Mozilla to move forward once he realized the bad PR was not going away no matter how hard he tried to fix or assure folks they had nothing to worry about. Obviously this is conjecture on my part.
To the people who say he resigned and was not fired: there is such a thing as "constructive dismissal", which basically means "forced to resign".
Both Mozilla and Eich publicly claim it was a true resignation and not a constructive dismissal: <a href="https://blog.mozilla.org/blog/2014/04/05/faq-on-ceo-resignation/" rel="nofollow">https://blog.mozilla.org/blog/2014/04/05/faq-on-ceo-resignat...</a> <a href="https://brendaneich.com/2014/04/the-next-mission/" rel="nofollow">https://brendaneich.com/2014/04/the-next-mission/</a>
The beginning of this blog post screams that the author doesn't care about facts.<p>"Mozilla (the maker of the Firefox search engine)"<p>Really?
