I regret to inform you that Mr. Kling and his browser have been pre-canceled on Mastodon due to his politics (support for DHH, Charlie Kirk, anti-DEI stances, etc.)
From what I can tell, Iceweasel is more or less a reskinned Firefox: there's some code changes to make it compatible with Debian's licensing guidelines, but it would be reasonable (in my opinion) to describe Iceweasel as 'Firefox for Debian'. And so are you also certain that the maintainers of Firefox comply with your requirements?
EDIT: Seems like they edited their comment instead of replying (kinda weird?), answering "yes" to my question. Perhaps I am a pessimist but I am doubtful that every single maintainer involved in Iceweasel complies with their requirements. And presumably this applies to more than just the browser: what OS are they using? What apps do they use? What phone do they have? What bank do they use? What car do they own? Etc. When you take such a hard stance against something over a refused pronoun PR (which btw was definitely chuddy of him), you nonetheless invite scrutiny against yourself, particularly when you say things like "You might be amoral, some of us give a fsck."
What I'm assuming is that 1attice is boycotting public statements, not actual impact. It's why JK Rowling is so hated but not Orson Scott Card: the latter is likely giving just as money money to objectionable causes but he's not being loud about it [anymore], whereas JK Rowling is being loud... very loud. And so buying Harry Potter merch becomes a litmus test for morality, but not buying Ender's Game merch. Alas.
Some people don't allow imperfection to stop them from achieving their goals to the best of their ability. Your takedown of Iceweasel completely misses the point.
Seems like Kling is a wee bit of a chud. The claim about human rights likely stems from the "trans rights are human rights" mantra and is likely is reference to this (https://github.com/SerenityOS/serenity/pull/6814) where Kling accused a contributor of bringing "personal politics" to the project for changing one instance of "he" to "they" in a markdown file. Since then he has, for example, apparently gone on to complain about anti-white discrimination in the workplace (https://x.com/awesomekling/status/1874518295350837401).
For what it's worth, the perpetually-offended progressive has become an annoying stock character in our culture. At risk of falling for Poe's Law, the commentor on that PR who said "The denial of non-male users and/or developers is sufficient reason to not use SerenityOS" is a perfect example of this. Another more contemporary example would be the seething outrage over Last Ditch Bar's new mask-optional Saturdays.
Ladybird have a "no politics" stance by the looks of things, what that really means is kind of up to you. Here's an article about it further, I'm biased against it and so is this article so take that as you will:
You mean the guy whose concerts went on as planned, and the online slacktivists screaming literal baby murderer at him have already moved on to the next $thing?
I originally had an comment about how the creators did support human rights but then I did more reading. While Kling is trying to be neutral with respect to this particular project, his (personal) politics outside of the project would have placed him in the extreme far right a decade ago (by U.S. standards, so ever further right by European standards).
Can you give some examples of these "extreme far right" beliefs, by which I assume you must mean beliefs that are so extreme that something like only 1% of the most right wing parts of the population could believe them?
