Jobs fire people ALL THE TIME over personally held beliefs or things they say/do outside of work

I thankfully (at least in my opinion) live in a country where this is illegal and it does seem well-enforced (I live in France). I understand this can and does happen in the US, but I still find it shocking enough for me to comment on it. The firing of Brendan Eich had a pretty big backlash so I'm not the only one.

Furthermore he proved his lack of morals and character by starting a crypto browser. This guy isn’t worth defending.

I do not use brave either because I'm not comfortable with the philosophy and whole crypto thing, but using that as a proof to "the lack of morals and character" of Brendan Eich is a big shortcut to take IMO. Ironically that quoted parts also sounds like something I normally would more likely hear from someone at the opposite side of the political spectrum - from what I guessed is your political affiliation - but I digress and my guess may be completely wrong (in any case, I don't care much, I just thought it may help me to make you get my point).

Then to make things clear, I'm not against boycotting companies due to the personal actions of someone you vehemently disagree with, I'm against the idea of insulting publicly both him and the projects he's affiliated with every time his name comes up. This is the very annoying and toxic part.
