Strange, I don't remember any Mozilla employees organizing and rallying for political causes in the 1990s, and Mozilla was certainly around, if not the dominant platform at the time. Gay rights was no less of an issue then than it is today, it simply hadn't been popularized by the media and endorsed by politicians and corporations.

Personally I find it abhorrent that anyone was so quick to rally against Brendan Eich. If we keep going down this path, all we'll be left with are people that change their opinions on a whim and flip flop on issues so quickly that they resemble politicians. I'd rather have a good leader I don't agree with on every issue, than a poor leader who's trying to pretend to be on the right side of whatever political stance is in-vogue.
