It wasn't Mozilla. It was the liberal-capitalist community that needed a good witch-burning to take well-meaning minds off real, general quality-of-life issues and onto specific quality-of-life issues. Since the bourgeois LGBT contingent has sold out the queers and other subaltern groups, they can easily be led (as we all can) to play LGBT Moral Majority for some other richie. Why, some day, they might be the richie leading the charge! But that's group dynamics for you: ideologies and religions require belief in some unprovable fact as the price of admission. Otherwise, they'd be all the same, and how would groups differentiate each other if they were all just human without pretense or artifice?
Anyway... the LGBT-and-allies community consists of a lot of people; they've got a powerful, established institutional infrastructure (see also Dan Savage, nouveau Democratic boss, quacking in time with the Adminstration about Russia in 2013); they believe they are motivated and informed by principles but in fact succumb to hermeneutics and peer pressure as they become insiders; they're broadly perceived as motivated by principle; they've had their morale managed over the past few decades to a just-sufficient level to stay hungry; they desire to be accepted as part of mainstream society; they're ignorant of what, who, where and why power (the ability to achieve planned outcomes) is; and they like all humans are easily led (the ones who think they're too sly for it are among the easiest).
So they're a natural, powerful and pre-paid covert militia for the business interests of the Democratic Party, playing the mirror role to Protestant Christians are the natural, powerful and cheap covert militia for the business interests of the Republican Party.
