Thank you and everyone else working on the Firefox browser and adjacent projects for your hard work. Don't let the noise of the internet lessen what you and the team have done and continue to do.
I'm sorry that happened. I wish there was some way to solve the "one jerk outweighs a thousand happy users" problem. I still vividly remember one guy being an asshole about my work on the Wine bug tracker a decade ago, regardless of how many happy users I know there were.
It's human nature, unfortunately. Reality television producers have known this for ages: the episodes that feature people who come off as irredeemable jerks always garner the highest ratings.
If that ever really meant something, it has been so overused in the last few years that it's impossible to pick out any needles of serious use from the general default trendy grain silos of despair.
I'm not trying to get all of humanity to give up sex. I believe we can do better, here on HN, in this one regard. I am that insanely optimistic!
