The whole tone of this post (and that sentence in particular) makes it sound like this person sees some kind of systemic shift in Mozilla, which seems like a stretch.
Over the last few years Mozilla has been focusing on making the web be a platform for applications. This is so 100% spot-on with their mission statement -- it's like Mozilla has found their true purpose, and that is more than just creating applications than enable people to use the internet (Firefox, Thunderbird). Now they're doing more to make sure the web is a great platform for applications (asm.js, Firefox OS). I'm assuming that, as CTO, Brendan Eich had a lot to do with that. It would seem natural to pick him to be CEO. But now people are making it sound like Mozilla has lost it's way all of the sudden.
Obligatory disclaimer: I completely disagree with Eich's view on gay marriage. At the same time, I think he's very qualified to be CEO of Mozilla. Ousting him is not what will ultimately lead to LGBT acceptance. He does hold a stupid belief, but I don't think that means he should be "shunned" and not allowed to contribute to (or exist in) the web community, where he has proven to be a passionate innovator. I've found that I don't like allowing myself to be polarized towards everyone in some group, even if it's justifiable to dislike them.
