It's less about Eich and more about the fundamental rights of association that are being eroded in this country.
Employment is an association. I don't know how it gets more fundamental a human right than "I don't fucking like you, so I'm not going to give you my money to work for me." But somehow this has changed in America and a "job" is some thing the government controls, and you are just a steward of. Don't like felons? Tough shit - some areas now won't let you ask about it. Don't like gays? Too bad, hire him or else. Racist? Well, sorry - hire that other-race woman or else.
It's all bullshit, needless bullshit. Eich was a liability to Mozilla, period. It's not fair, he wasn't out proselytizing or burning crosses - sure. But he was a liability and Mozilla did not want to continue to employ him in that role. That should be their choice.
You can get blacklisted in this country for making a slightly off-color joke, or for "appropriating" a dance from another "culture". And yet we feel we need the government to step in and manage all employment in this country to an increasing degree.
