Meanwhile Mozilla the organization boots people for politics, wants "more than deplatforming" and uses as one of their examples organizations deciding what I should see on the Internet - preferring outlets that Mozilla themselves like, naturally. They publish stuff with the gist of "did you encounter other politics on YouTube, how scary".
Meanwhile the organization spends money on getting a sneaker designer to make time-limited color themes for their browser and writes a pile of copy about how cool it is that a sneaker designer painted the browser blue.
Meanwhile, Brave releases a user-customizable filtering function for their search engine so you, not someone else, can decide from what POV you see the Internet and added native vertical tabs to the browser.
One organization is blatantly political, the other just makes a good browser.
You can run a similar set of comparisons for Vivaldi, who are also clearly a much more product-focused organization and it shows. They have some more visible political leans as an org, but still far milder than Mozilla's, a lot of those leans being just being vehemently anti-crypto, with the biggest focus going to user control and privacy, as it should.
But yes, Eich and his horrible treatment of gays, which he still hasn't renounced (instead doubling-down and saying that the "deal" was that they could have civil unions but they went too far to get marriage too — they can ride on the same bus, but they can only sit in the back), as well as his nonstop promotion of conspiracy theories is something no sensible person would want to support. If you think Mozilla "[booted Eich] for politics" instead of for taking public actions that tarnished the reputation of the company, you seem like the type of fellow who would have cheered Stephen Douglas in the Lincoln-Douglas debates. As Douglas repeatedly stated, laws concerning the sale of "negroes" are no different from laws concerning the sale of dry goods or liquor, and the people of Illinois should no more tell Missouri how it can sell people than it should tell them how it can sell dry goods — that's Missouri's politics, and Illinois should mind its own business.
You do if the word has a legal definition and you refuse the benefits tied to that legal definition. Eich is free to call it whatever he wants as long as people get the benefits of marriage, something he paid to stop from happening. What kind of asshole thinks it's OK to treat someone poorly because of quibbles over how everyone else is allowed to use a word? For that matter, Douglas is free to call black people "human goods" so long as he doesn't allow them to actually be bought and sold by controlling legal definitions that allow for it.
