Mozillian here: Mozilla is not a company like Dropbox. Mozilla is first and foremost a community. We don't wait for our leaders or our PR team to decide whether we defend someone. We do it from the roots, and that's what many of us did (see the community blogs at http://planet.mozilla.org). Others in the same community decided to attack Brendan's position, which is just as acceptable.
Now, you are right, Mitchell Baker's statement is very apologetic. Remember that she is (or at least was) long-time friend with Brendan Eich and that she probably was hit very hard by the tsunami.

That sounds find in principal, but it wasn't effective enough. As a strong supporter (and very minor contributor), please take this the right way: Mozilla needs much better public communication; it's a continuing problem IMHO. In fact, arguably Mozilla depends on public goodwill more than the for-profit companies.
