Mozilla backed Eich the whole way as far as I remember. They initially shrugged off rarebit's reaction with the standard "we should all respect personal opinions" (except for the personal opinions of people affected by Eich's actions, of course).
It's not the message, it's how it is delivered.

In any event, there have been plenty of regimes in history where you needed to be a member of The Party and toe the party line... and if not, you'd be ineligible for any position of power, and maybe out of a job. Perhaps your nation had a revolution, and the party in question is Communists. Perhaps it's merely a Reformation, and you're just not allowed to be Catholic anymore (or a counter-reformation, and you're not allowed to be Protestant). Maybe it's just the local banana republic.
And this is purely a partisan-affiliation play. No one has seriously asserted that Eich was mean to any individual gay person, influenced company policy in a way that said gay people are unwelcome, or anything of that nature.
In any event, it's quite clear that at least some portion of our society -- the one Mozilla operates in -- works under the guiding principles of those regimes. How modern of us!
