That's not what he did. He donated for California's Prop 8, which opposed same-sex marriage, in 2008. I'm personally not judging, as many US progressives have forgotten that during those days, even Obama opposed same-sex marriage. But it's important to get the facts straight, even when being sarcastic.

Mozilla's management certainly is guilty of blunders, but I'm pretty sure the developers who have worked on Mozilla don't feel like they've spent time “politicking”.
The failure of Firefox in the marketplace starts from the fact that it's pretty hard to compete with a browser that's funded with more than 1 billion $ per year. And people may not remember much about the launch of Chrome, but it was literally years ahead of its competition. Have a look at its famous comic book, with which it was announced, describing its design and philosophy, and count the years it took for the competition to catch up (across the board, including Safari): https://www.google.com/googlebooks/chrome/
I mean, sure, you can blame that on politics, but I don't think anyone was able to stop the decline and when Brendan Eich resigned, people were already talking about Chrome's hegemony and Firefox dying.
And remember -- the original browser engine that Chrome (+ Safari) came from was KHTML + KJS from the KDE folks, which was doing pretty good at the time considering the development resources available to it
One day the wokists will be trialled like the Nazis.
Firefox compliance is another story, but very mild compared to IE. Chrome also had to deal with compatibility issues when Firefox was the leader, but Mozilla relinquished their leadership position because it was very important to them to fire their CEO / original writer of Javascript for ideological reasons - he had given $1000 to an anti-abortion NGO, which is an unacceptable thoughtcrime. Then they spent their time politicking and not enough coding.
Sounds like the history of browsers is just made of strategic mistakes.
